Tool/software:
Hi TI,
Webench shows I can achieve 1000V/1W output by UCC28C51-Q1 (input 9~16V). I would like to use flyback IC to control a 10kV/1W output flyback.
First, I build a 10kV open-loop topology as schematic below.
Vin=12V, Fsw=20kHz, Duty=50%.
I have 2 questions now.
1. Why the primary-side current of XFMR is a sine wave when MOS is turned ON?
2. Why Vout doesn't increase when MOS is turned ON in negtive current period?
Ch1: MOS Vds, Ch2: Vout, Ch3: XFMR Ipri
