Hello. I am planning to build an 12 channel DMX dimmer. Right now I am figuring out the power part of the project. After some research, I decided that I will try to make trailing edge AC phase cut dimmer with an IGBTs. While googling for solutions, I came across this dedicated IC: FL5150[/URL
Hi! I'm designing a grid tie inverter. The important thing is it's synchronization with grid sinusoidal waveshape both in phase and frequency. I was planning to use PLL 4046B IC who will be given power from Vdd = 5 VDC. I'm not used to PLL so much so my thinking was that it will generate a sinusoidal wave of same phase and frequency as input gri
can anyone pls explain some of the circuit principles affected by layout such as speed, power, noise & area??? Thank you!!! :)
Suppose we need to insert horizontal and vertical stripes in power planning. What are the considerations we should take to decide which one has to be placed first? Or can we place either of these stripes first?
You mean like one of these chips.. ..what you are asking, the “silicon floor planning” of it, well, I always assumed that was secret info held in top security by those fab houses who know it
I am planning for a drive using 6 lead stepper motor voltage is 12 V Winding Resistance is 25 ohm. ULN 2003 or ULN 2803 seem to be insufficient in terms of total power handling capacity. Any advise for a suitable d
Yes, it should be terminated with a 50Ohm resistor with minimum parasitics. Output powers are correct, however you may experience loss due to microstrip lines.
Hi All, I am planning to build a 5v power supply which can provide at least 50A. I found many project on internet that use MOT (Microwave oven transformer) it can produce a lot of current. I am focusing now on the losses and low ripple DC voltage. I am planning to use Pi-Filter to remove the AC ripple voltage (Forget about values in (...)
UPS requires battery charge and storage for DC-AC inverter to provide power when grid power is interrupted. These are called 2 stage UPS. A good design avoids power interruption, glitches and brown-outs that may drop your PC PSU , "faster than a rock", since they are designed cheaply to have only 1 cycle of storage capacity at line speed, (...)
70 MHz filters are IF filters, so there's no reason to design it for power handling. I see a +23 dBm rating for some GSM filters, I would expect similar numbers for 70 MHz filters. Without a specification, I won't hesitate to expose it to low power like +10 dBm.
Hello, I'd like to ask just a quick sanity check question about my approach in my design. I'd need to know what is the most reasonable solution to switching high loads, such as 12V solenoids/relays within low-power(e.g. battery powered) system? I'm planning to use 3.3V MCU(to save idle consumption), for which the load is driven with a (...)
I agree with FvM I also believe for high power 3 phase bridge drivers for high efficiency single phase is best for apps >>100W resulting in low dynamic losses. If you can limit the load swings 2 phase half bridge (with ventre tap making a full bridge) can work. But if not , well then valley sensing on current to commutate is better. Recall time
Hi my friends i have a problem in add strip in 45 nm tech when i add strip i see this warning in shell window " **WARN: (ENCPP-2008): AddStripe option -remove_floating_stripe_over_block is ON so all fragmented stripes within a block will be removed. To turn OFF, setAddStripeOption -remove_floating_stripe_over_block 0. Starting stripe ge
Hi all, Could anyone help me to calculate the power of a chip? Any formula to size and offset of stripes, power rings? Thank you
Hello , please I need a circuit that can help power electric pressing iron or cooker using small generator or inverter.. Thanks
Hi Guys, I have this power supply w/c originally an N-CH Mosfet installed with this rating. Vdss-500V Id=24A Rds (on) .23ohms Right now, I am planning to change with IGBT type with this rating. Vces-1200V Ice-40A Vce(on)-3.2V Is it acceptable? Normally in changing the power Mosfet, what are the things that need to (...)
HI All, I would like to know how to force SOCE to use exact types of vias for PG connections. Is it possible in SOCE? Is someone aware of it? Thanks in advance. Regards, Vahe
Hi All, I am planning to build a light with 10 Watt LEDs. These LEDs work on 32 V. What do you think of connecting 6 or 7 of them in series and power it with 220 V Ac? Regards, Devil
My focus is on MAC unit to reduce its area and power dissipation.I'm planning to code multiplier unit by using vedic or any other technique. Can anyone suggest a good modification on this MAC unit? thanks.
Hello i'm planning on build a dc electronic load and i want to make the constant power and constant resistance modes analog so i can just put that in a feedback loop rather than constantly sampling -> making floating point calculations -> outputting through the dac so i need your help with an analog multiplier/divider circuit/IC whichever possi
