Totem pole PFC circuit control method, control device and electronic equipment

The embodiment of the invention provides a totem pole PFC circuit control method, a totem pole PFC circuit control device and electronic equipment. When the input voltage of the totem-pole PFC circuit is in a negative half cycle, an upper switch tube of a fast bridge arm of the totem-pole PFC circuit is a main switch tube, a lower switch tube of the fast bridge arm of the totem-pole PFC circuit is a follow current tube, and the control method at least comprises the following steps: controlling the upper switch tube to be conducted; judging whether the conduction time of the upper switch tube reaches the maximum conduction time or not and whether the peak value of the inductive current of the totem pole PFC circuit reaches a peak value current reference value or not; if the conduction time of the upper switch tube reaches the maximum conduction time and the peak value of the inductive current is smaller than the peak current reference value, charging a bootstrap capacitor of the totem pole PFC circuit; after c
