Hi,
I investigated the "Test Report: PMP23126", document name:TIDT275.
When load current is increased like "Figure 3-4. 150-A Load" and higher currents, the primary current waveform has a DC mean and mismatch at tranformer current. This topology has PCMC implementation in software.
I would expect not to see any mismatch in current waveform because control technique is PCMC. Can you evaluate the condition and explain the reason briefly?
