Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

hi,
just signed up to share this.
since i followed and used some of the info from the topics regarding the powerjack 300w grid tie inverter

Scrubbed component U2 appears to be a PWM controller
part number depends on component manufacturer but heres a short list

U2, onsemi - SG3525A or Fairchild - KA3525A or TI - UC3525A

they are all the same

Also,
Q4, Q5, marking 718 is FMMT718 pnp transistor
D5, D6, marking ZS1 is ZHCS1000 schottky diode

reason i worked this out. I wanted to check if the MOSFETs were specced correctly for there application
my gti blew the MOSFETs Q6 & Q1 STP75nf75Edited by lambcutlet 2011-10-24
