Hi, I am using Hyperlynx 8.1. I created a multiple layer PCB. I am not able to edit the Zo value of plane. Even If I change the Z0 value to zero, it automatically changes to 75 ohm. In general, Z0 is zero for ground and power plane. It will be helpful If I get a support.
My objective is to convert voltage and current simultaneously in an atmega controller and to find the power by multiplying it. I've written the following code for ADC conversion: interrupt void adc_isr(void) { data= ADCW; if(adc_channel==0) { voltage_data_available=TRUE; adc_channel++; } else if(adc_channel==1
Hz2020, There is no mistery on designing of a SMPS with multiple outputs. You must to perform the same step required to 1-output, but adding as windings at transformer as required. If it is not desirable ground these outputs, just donīt do that. The remark gave from mrarslanahmed is that PC power supply is a good example, and if you "cut" g
Hi How to determine how much heat sinking is required for multiple mosfets?? if I know how much power each one dissipates. I know how much heat sinking I need for one. These mosfets are mounted on a Bus bar, which acts as a heat sink. Thanks
Normally I would use the inner power layer to route the multiple power supplies using wide tracks. You shouldn't need extra layers. Keith
If you have a factory with multiple high power machines you might have a 300 A incoming breaker (three phase + neutral), feeding 4 busbars along the back of the cabinet. There would also be a earth busbar. So machine #1, would be fed by a 50A isolator, which would have three phases running through it, each being connected to the busbars with a pie
as you replied there is something wrong with your extraction and layout. I am attacing both ,I couldn't find out where I have done mistake. As already posted multiple times: If you have set Rs=100 Ohm, your "long" resistor with length/width = ~10 will have ~1kOhm resistance, instead of the 100 ohm that we want.
Many devices will have multiple VDD and GND pins. So even if some of them are powered, the device will work. But it's a good practice to connect all the applicable pins to respective power/ GND. Because there could be some devices where different pins may be powering different blocks of the device. CPLD and FPGA are the best (...)
In my view the GND will be common from the input supply .....this is common when you have multiple power derivation.....I don't see any harm for the board.....but if you really fell that you need to have protection for 18v and 5V use split plane connection and will have common connection made with inductor in series....However this technique is uni
If i assign multiple ports say 10 wave ports so the software should excite the structure with all the ports ,but the ports assigned first will only be able to exite... why?
Hi nitin, this is a common practice to have multiple power domains in a SOC. Yes we will need to use a level shifter when switching between power domains.
That image shows 64 LEDs addressed using 16 pins. You can multiplex them to achieve more individually addressable LEDs per number of pins. You need to use a microcontroller or something with programmable tri-state pins. The maximum number of LEDs for n tri-state pins is . The code is more complicated, but with 16 pins you can control 1
Referring to mtwieg's doubts, I think there's a chance, that the multiple converters will cooperate in a reasonable way with just parallel connected Ith pins. You won't want to use additional diodes, because they dwart the converter efficiency. To get full advantage from paralleling the converters, you can supply a multi phase clock signal to sy
Greetings, I'm building an obscuration meter which uses multiple high power IR LED to illuminate sample, then a photodiode is used to measure transmittance. Since external IR-sources and noise are distorting results significantly, I've utilized phase sensitive detection to minimize errors. However due to this I've got to drive IR LEDs in sine(ac
PC power supplly will have two sections one is flyback converter serves as standby power used to turn ON main power, other one is PWM switch mode power supply serves multiple outputs. Standby power is 5V supply allways ON aslong as line power is available. using the colour (...)
guys ,,, How can I make a circuit that can control AC power supply to give me multiple values !!!!
Most commercial DC/DC modules are using flyback for multiple output modules. It's the only way to get off without secondary regulation or other multi stage designs. Input ripple can be LC-filtered. Inter-windings capacitance and respective injected interference current are a more serious problem in isolated DC/DC, I think.
Hi, if we are designing a power supply having both positive as well as negative outputs w.r.t output ground. what technique is used to sense outputs if we want to take feedback from all negative and positive voltages at outputs in this multiple output power supply.
Hi i'm designing a half bridge based converter of around 300 watt output power. it has multiple outputs. it has 5 outputs excluding auxiliary supply winding which power chip on primary side. i have simulated it on PSpice. but not proper regulation of all outputs using simple coupled inductor technique like used in ATX power (...)
I understand you are talking about TSMC I/O structures. If you have little more time you could design your own I/O. Schmitt - no you do not need to have it but it is very good idea. If you have multiple power supplies you should have ESD protection between them - unless it is a test chip and you are aware of ESD risks.
