Part Number: TMS320F280049
Other Parts Discussed in Thread: TIDM-02000
I am trying to realize PSFB PCMC operation based on the TIDM-02000 sample program.
As shown in the attached photo, where you want the transformer current to appear symmetrically up and down, the control on the positive side becomes large. Do you know what the cause is?
When I checked in open loop, the current was asymmetrical.
Will there be an offset in the current detection circuit because the current is asymmetric?
Does the current become asymmetric because there is an offset in the current detection circuit?
The measurement environment has changed, so the oscilloscope waveforms have changed, but from the top they are QA, QC, QD, and transformer current.
