Beschreibung
Zusammenfassung:	A circuit with a metal-oxide semiconductor field-effect transistor and a diode module is applied to a power factor correction circuit, which can effectively reduce the heat generated by the whole system under heavy load, The circuit includes a metal-oxide semiconductor field-effect transistor and a diode module and a load determination unit. The diode module includes a plurality of diodes with a switch. The load determination unit can control the connection/disconnection of each diode in the diode module based on the magnitude of the load current. It can effectively reduce the current generated by each diode due to the load, thereby reducing the heat generation of the overall system. Moreover, due to the contact capacitance effect after the diodes are connected in parallel, the electromagnetic interference (EMI) characteristics of the power factor correction circuit of the system can be further optimized.
