Gate Drive Transformer
I am building a gate drive transformer, for a HALF BRIDGE power supply, the A-AND-T-LABS power supply, www.a-and-t-labs.com
Since the company as it looks, is closed down, they are no longer responding to e-mails, however
I decided to build the power supply from scratch, I have all the parts now, assembled the PCB, all OK.
The only problem I have is the GATE DRIVE Transformer.
winding as follows
14 Turns Primary
12 Turns Secondary 1
12 Turns Secondary 2
12 Turns Secondary 3
12 Turns Secondary 4
The core I am using is specially designed for GDT, form Coilws.com
Each secondary will drive a MOSFET IRFP450. to make 2 mosfets out phase 180 degree with the other 2 mosfets.
I am unable to make Secondary 1 and Secondary 3
180 Degree OUT OF PHASE with Secondary 2 Secondary 4
I tried to wind in deference ways, but I failed to make it work
ANY help with this issue is more than appreciated.
how to wind it in the right way to accomplish that!?
