What power rating do you plan to make ?
Hy I am designing a power distribution board using the OR-ring topology. The board has to carry about 34A per contact ( and 140A in the common nets. In order to route the power nets I have used a copper pour area in all the 4 layers. I plan to use 70um copper for both external and internal layers. I have checked Saturn PCB (...)
Hi, I am Trying to build a BLDC motor controller with the PIC18F4431 MCU. My plan is to use the six step sensorless trapezoidal commutation. Complementary and unipolar PWM, to be precise. The reason I chose this is to use synchronous rectification instead of simplt using the MOSFET intrinsic diodes. This means that, at any given time, both MO
Hi I have a situation of low GSM signal indoor and I need to amplify it I have seen some boosters availble but I wanted to know is it possible to amplify gsm signal using active GSM antennas ? I have some active antennas gor GPS and GSM and they have LNA inside my plan is to use these antennas and supply them with dc power supply have you
hi everyone i have problem with my semikron skiw 700 this for welding power controller. the problem is the trigger is not function fast enough, i plan for modification with a simple trigger, but i don't have the diagram. If anyone can give me a simple diagram to trigger this SEMIKRON SKiW700 ? I wait for you all the solutions of the electronic
Hi, I want to test an LNA IC. I want to use supply of 0.7V and make it as low noise as possible. I plan to use a 6V lead acid battery and then use a voltage regulator as follows Can anybody suggest better ways? The lab power supplies that I have make the noise figure 1dB worse.
Different touch sensor designs are more or less sensitive to 50 Hz hum and high frequent noise. So you should describe your touch sensor setup thoroughly. I guess, grounding the power supply output would help against both possible interference sources. If you plan an isolated power supply, an Y-capacitor would at least help against high (...)
I have taped out a chip for low power ECG acquisition. I have to plan to test the chip when it comes back. Regarding the same, I would like to have some information about the test set-up used for the testing if the chip. What are the instruments used for the testing -company and instrument number, specs Whether the input ECG is a rea
If you plan 50 Hz frequency, then a 4H primary inductance is reasonable. That is the default value when I place a power transformer in the simulator (Falstad's). However as post #2 states, you can make the frequency faster, allowing you to reduce certain parameters for the transformer. [
Are you asking if you need something between the power supply and the motor? If it's a 12VDC motor you can safely apply the 12V power supply across it. If by ignore the transistor and resistor you mean you don't plan to use them then that would be an issue. The Arduino pins cannot source or sink anywhere near 950mA. If you
That comparator does appear to have a push-pull output. You need a new plan. ;-) You can't connect the comparator common to the ground that you are disconnecting from the battery negative terminal. If you want the battery to power the comparators then you need to connect pin 4 directly to the negative terminal of the battery.
I am looking to create a bluetooth wireless variable speed motor that can be that can be controlled from a phone. The pcb needs to be about 3cm (or smaller). How would I go about doing this? I plan on using a AAA battery to power it.
Hi Guys, I've this question. I'm using a HDMI converter chip which convert from another display format to HDMI. For the core voltage which run at 1.2V , they specify quite a tight requirement on core power supply: 1.1-.13. I plan to use a fast transient LDO for this power supply since it's going to power the core cput (...)
If your application doesn't need 5V, it would be more appropriate to convert to 3.3V in the first level, particularly if you plan to use linear regulators. You should have a rough idea about the current consumption of each power net, e.g. by using the Altera power estimation tool, to decide if linear regulator are accpectable. Starting (...)
Do you plan to power a turbine via fluid flowing from the tanks? The fellow in the video forces water from a hose into his homemade turbine to spin it at high speed. This is one way to do it, as long as you have tools that allow precise work. To build a spinning armature requires that you be able to balance it, center the axis, etc. His gadget lo
You will want to specify the Voltage and current of the LEDs and power source available to amplify the signal. and drive the LED current to control brightness. 12-24V is a wide range. Do you mean 12~14V? Do they have electronics included for fixed power?
NPN power are preferred so a PNP Darlington is preferred with PNP driver to NPN. Only one means square root of linear current gain product and 1/10th the saturated gain at Ic/Ib=10 for each stage.
Usually a flyback is employed for these types of aux power supplies...., but a fixed push pull can work, you need to avoid the chokes in the o/p rectifying ckts...
My specifications are as follows: 2 in phase 120V lines 1 Neutral 1 Ground So, I should use a 240V GFCI, right ? This is the one I plan to use. 23250 003-1 GFCI So, connections would be connecting one 120V line to the line wire on gfci, 2nd line wire to the sec
How do you plan to convert the 3V to 9V efficiently? Is 3V the MPT operating voltage (max power transfer) or the open circuit voltage and short circuit current at max solar input power? I assume you phone uses 9V input down to 6V? Is that a Lithium rechargeable 9V cell? I think a 1N4100 (not IN4100) is a 7.5V zener and the
I plan on using the qflowl for design exploration, but I need power and/or energy numbers for this task. Does anyone know of a FOSS tool for power analysis?
LM2700
These rating look good . Does the input capacitance of the device feature in the power supply design e.g. is it part of a SMPS, in which case you must make sure you have enough drive capacity. Frank
I would like to replace a USB 3.0 connector with a circular connector and I am not sure how I should go about actually verifying that the new connector has sufficient signal integrity. I want to do this because I need to add more power to a device and only want to use a single removable cable. My plan is to get a custom USB cable made with addition
If you aren't going to add internal power plane layers and assign one of them to the GND net, then you'll have to add a plan or poured region or set of traces on the bottom layer and define them as connected to GND. Do you have an account on the Altium forum? In the PCB layout, since you don't have an already defined (...)
I have been working a little bit on a hobby project of mine involving inductive power distribution. I have never done anything like this before and before I hook things together I would like to avoid blowing stuff up. I plan on powering between 1 and 3 inductive loads (i.e. hand-wound coils about 4-6cm in diameter shaped like a ring with (...)

hey everyone, i am working with an LTE network deployment so i have to plan in terms of different propagation losses. the chosen propagation model is COST-231 model however, i have no idea how to derive the data rate, antenna gain, path loss, noise power. all these things have values and i do not know how to work with them. any help will be
Please, I have a transformer with a 10V x 100mA secondary. I plan to power an MCU based project with it, but my problem is: 10V is much more volts than I need, I plan to power my circuit with 3.3V at most. And 100mA of current is too low, I need more. So I'm wondering: is there a way to reduce the volts to 3.3V, and (...)
Due to limited selectivity of the RF filters, RF gain can't be arbitrarily high, otherwise off-band components could cause amplifier and mixer overload. So if you plan higher RF gain, you have to check that the signal is keeping the linear range in every part of the receiver. When we said that the RF amp has input power is -110dB
Dear All, I am planning to implement an MPPT algorithm for solar powered battery (Lead Acid, 12V, 7Ah) charger. The solar panel is a 50W one. At peak power it can give 18V and 2.78A. It has a Voc of of 21V and Isc of 3A. I have some querries regarding the design I plan to do, which are: 1. Which converter topology is (...)
ADS ships with everything you need. Just open a new schematic and select Insert > Template... then select and place the HB2ToneSwptPwr template. Drop your LNA into the schematic (with necessary voltage sources) and set values for RFfreq, fspacing and in the Sweep plan set the input source power parameters. The resulting data display includes pre
The power pins will be added in the encounter tool at the floor plan step.
In a 20-Amp power supply, use the thickest conductor available, and connect the marked points by screws to a thick aluminum chassis. Also make sure the grounds in the AC input and DC output connectors are connected this way.

Hi all..... I am now learning the Place and Route using SoC Encounter version 9.1. But the document given with this version is compatible with the earlier version (Version 8.1). So, some of new tool functions are not described properly in this document. E.g. in the document there is an extensive use of Synthesize power plan option whereas
You plan to power one led rated 100W or 200W or several in chain ?
Hi. 1. Consider this question: Do you need a fast diode? 2. answer to your first question will lead to this answer. 3. Where do you plan to connect this dummy load then? Is power loss a problem?
May be used a parallel connection between internal power supply and battery (eventualy small resistor for current limiting). In this way power supply keep charged battery, and feed power to circuit. If battery is externaly charged or have a separate charging circuit, may use a diode (2 or 3 in series) to isolate battery from internal (...)
