Nov 30, 2019 · Somehow I thought this was a push pull, but its a 2 trans forward, the gdt is wired in phase so both trans's are on at the same time. D7 and D7' conduct when the igbt's are off to …

Apr 20, 2022 · Hi, Do you know why the switch S3 in the attached LTspice sim is not working? Ive been doing switches like this for 10yrs plus, and never had one like this not work.

Oct 13, 2013 · Ok, thanks to ChrisP58 in another thread, he suggested the possibility of changing a circuit design with a single Primary GDT and offered the Center Tap GDT. He gave me a …

May 24, 2017 · The problem I'm having is to see my GDT Waveform correctly I need to ground on one output and probe the other on each separate coil. Now the low sides are tide together at …

Feb 9, 2009 · Hi I intend to use a MCU pin to control, via a npn transistor, a 9V DC relay coil which switches on the primary of a transformer (inductive load?) of a device. Let's say the load …

Aug 13, 2015 · If you want to step up the voltage than you can use a gate drive transformer, you could use such an item with the gate driver ron mentioned, you get step up and isolation with a …

May 24, 2017 · I did notice when trying a bunch of values it would change the output voltage of my GDT significantly. I went with the highest output as well as best looking waveform. But I'm …

May 11, 2012 · So we use an MOV, GDT, avanche diode, etc to make that earth connection. Critical is not the protector. Critical is how a connection to earth is made. For example, if a wire …

Sep 29, 2013 · Actually it's just not in the Database, need a 1uf MKP Cap and a 12v zener, along with the SG3525? Thank you. kv

Sep 19, 2015 · Maybe thats been done to balance flux in the transformer core or some emi reason, kinda makes it tricky as the drive voltage for the high side fet needs to be higher than …
