Title:
CONVERTER AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/186562
Kind Code:
A1
Abstract:
Provided is a converter applied to a power system, with the power system comprising a first power supply apparatus, an energy storage apparatus, a second power supply apparatus and a load. The converter comprises a first power supply control module, a bidirectional inversion control module, a main control module, a direct-current busbar and an alternating-current busbar. The direct-current busbar is connected to the energy storage apparatus, is connected to the first power supply apparatus by means of the first power supply control module, and is connected to the alternating-current busbar by means of the bidirectional inversion control module; the alternating-current busbar is connected to the load and the second power supply apparatus; the main control module is connected to the first power supply control module, and is used for converting electric energy output by the first power supply apparatus into a direct current power with parameters matching power source parameters of the energy storage apparatus; and the main control module is connected to the bidirectional inversion control module, and is used for controlling the bidirectional inversion control module to perform mutual conversion between an alternating current power on the alternating-current busbar and a direct current power on the direct-current busbar. By using the present application, the circuit structure of the converter is simplified, and the energy storage apparatus can be reversely charged.
