ChrisP58 Well-Known Member Most Helpful Member Sep 9, 2021 #22 These voltage wavforms look reasonable for an open loop converter. The L24 current looks excessive, although I don't know what your load is. But the voltages within the waveforms are nowhere near those on your schematic of post #3 What's changed? PS. The time windows shown are wider than is useful to see the basic operation. I'd prefer a window of 5 or 10 cycles.

I'd prefer a window of 5 or 10 cycles. Click to expand... The load is three DC-DC converters connected on the output of the SEPIC. I didnt change many things. Post #3 is to show the schematic so dont pay attention to the voltages. In respect to the time, for what time for example you suggest to run?
