Abstract: A free-wheeling diode control method includes determining whether a sum of a first pulse width value of a free-wheeling diode obtained according to an inductance current law and a third pulse width value of a main control tube meets a first preset condition, obtaining a determining result, and controlling, according to the determining result, conduction of the free-wheeling diode according to the first pulse width value or a second pulse width value of the free-wheeling diode obtained according to a volt-second balance law.
