COMPATIBLE POWER SUPPLY CIRCUIT AND CONTROL METHOD THEREFOR, AND CONTROLLER AND STORAGE MEDIUM

Document Type and Number:

WIPO Patent Application WO/2024/045370

Kind Code:

A1

Abstract:

Provided in the present disclosure are a compatible power supply circuit and a control method therefor, and a controller and a storage medium. The compatible power supply circuit (100) comprises: an auxiliary power supply (110), which comprises a first input port and a second input port, wherein a first capacitor (101) is provided between the first input port and the second input port, and the second input port is grounded; a photovoltaic power supply unit (120), wherein a first photovoltaic output port thereof is connected to the first input port by means of a unidirectional conduction unit (140), and a second photovoltaic output port thereof being grounded; the unidirectional conduction unit (140), wherein the conduction direction thereof is consistent with the flow direction of a current output by the photovoltaic power supply unit (120); and a power grid power supply unit (130), which is used for converting an alternating current on a power grid side into a direct current, wherein a first power grid output port of the power grid power supply unit (130) is connected to the first input port, and a second power grid output port thereof is grounded.
