Dear All,
I am trying to perform a PSS analysis of a multiphase DC-DC converter. However, the analysis is failing due to convergence problem.
But the PSS (and followed by PAC) on single-phase topology works just fine and gives correct result.
I am suspecting due to multi-phasing the PSS is failing. There are 5 phases in the system with fundamental period of 2 usec. So, each channel is phase-shifted by 400 nsec. And the output ripple period is 400 nsec. I have specified the beat frequency as 500 KHz (1/2usec.) is PSS analysis setup.
If the problem is happening due to multi-phases, then what is the solution?
Regards
Sam.
