I am trying to do a cascaded control for boost power factor correction circuit. Currently I am trying to test the current control loop alone. But the problem is the high frequency switching of my MOSFET switch is not happening.Can someone help me with this?

Hello Ashwini!Something seems to be amiss at the output of the diode bridge rectifier.Can you monitor the signal there?If there are harmonics, try adding a shunt cap. at that node.
Best regards,
Justin

Current control systems of single-stage help PFC converter were reenacted and help with assignment writing the outcomes acquired from the reproductions are analyzed for more profound understanding of the control procedures of PFC topology. These control systems are top current mode control and hysteresis current mode control.
