In a previous state than t0, the inductor was energized through Q1, which would implement the switch function in a totem-pole PFC. Once Q1 is turned off, the inductor current flows through Q2, first through its body diode and then through the channel of the device, once Q2 is turned on...
In the TPPFC circuit, when the AC mains connection to L1 is positive, Q1 forms the boost switch, Q2 forms a synchronous rectifier, Q3 conducts to allow line current to circulate and Q4 is blocking. When the AC input is negative Q1 and Q2 swap roles, Q3 blocks and Q4 conducts. At...
