Smile 1.2 kw Full bridge with SG3525 ACMC and VMC

Hello all.

I am not familiar with the average current mode control technique. I have built a system comprising of a sg3525 and a pic16f72 which controls the SG3525 for variable power. i have the SG3525 and the PIC sitting on the secondary. The gate drives are isolated pulse XFRs. The voltage mode is doing just fine - waveforms on the scope have been like asthough traced from a refbook - snubbers' doing a good job. I have been having trouble with average current mode control.
