Title:
BIDIRECTIONAL DC CONVERTER COMPRISING TWO TYPES OF MODULES AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/196609
Kind Code:
A1
Abstract:
Disclosed are a bidirectional DC converter comprising two types of modules and a control method therefor. The bidirectional DC converter having a higher power level and a higher voltage level is formed by two different types of isolated DC-DC converter modules, which are respectively defined as type I module and type II module, one ports of the modules being connected in series and the other ports thereof being connected in parallel. The number of used two types of DC converter modules is not limited; however, for each type, at least one DC converter module is used. The two types of modules each at least comprise one isolated DC-DC circuit. Type I module further at least comprises one DC-DC converter of which the power can be automatically adjusted, and a circuit structure form of type II module is different from that of type I module. According to the bidirectional DC converter and the control method therefor of the present invention, integral bidirectional power and voltage adjustment for a DC converter can be achieved according to a combination state of different types of modules.
