input current waveform Issue in Totem pole PFC with Synchronous rectification

Thread Starter

I am designing a Totem Pole PFC with Synchronous rectification at the slow leg. When is simulate the Topology in the open loop I get undesirable Results for the input Current waveform can someone help me with what is happening?. I used Duty as 0.5 with a 100kHz switching Frequency at the fast leg and a 50Hz 0.5 duty ratio at the slow leg. I Tried changing the Duty ratio switching frequency and phase shift inductor-capacitor values but this error still occurs Simulated Topology.pngUndesirble input current waveform.png
