Hi,
The attached shows a 100Apk 50Hz current source to do "PCB trace high current testing".
This is the well known "error amp closing the loop on the bridge current" method, which pretty well designs itself.
Its also seen splashed literally all over the internet.

Do you agree that the series General purpose diodes shown will be needed in order to p...

Hi,
The attached shows a unipolar CST with two secondaries in a PSFB input. This will result in less magnetising current peak in the Currnt sense transformer.
Do you agree its the best way to counteract the fact that the primary of the CST will have bipolar current in it? , as is normal for the PSFB.

LTspice sim and PNG scm attached.

Hi,
We are doing an induction motor and have produced the 50Hz , 90Apk sinusoidal current waveform using a H bridge with Vbus = 120VDC. (at least we have it on sim and believe it to be a ready-able solution...i mean no secrets here, a H bridge with a current sense into an error amplifier with a sine ref is the "noddy" well-known solution here anyway...no secrets to be give...

Hi,
Was just looking into GaN for a high pulsed power application.
The situation of a GaN FET in anti-pllel with a SiC diode appeared to offer the advantageous abscence of any reverse recovery.

Then found out that GaN is only cheaply available as GaN-on-Silicon. And GaN-on-Silicon has terrible expansion/contraction issues which may get brought out with v...

Hello Guys,

I need help regarding a 6 channel Transmitter and Receiver PCB design, build using Atmega-328p and NRF24L01+ PA & LNA. I have a design whose range stuck at 400 meters but I need to achieve 900 to 1000meters. I have tried many pcb designs but when i try to shrink the pcb form factor the range also dropped. Can any one can help me regarding this.
