Document Type and Number:
WIPO Patent Application WO/2022/017391
Kind Code:
A1
Abstract:
A totem pole PFC circuit and a control method therefor, a circuit board, an air conditioner, and a storage medium. The totem pole PFC circuit sends a pulse signal to a third switching device at the positive half wave of an alternating-current voltage signal and to a fourth switching device at the negative half wave of the alternating-current voltage signal by configuring a controller, so as to form a first oscillating circuit and a second oscillating circuit, respectively.
