Title:
BIDIRECTIONAL POWER CONVERTER, ELECTRIC AUTOMOBILE, AND METHOD FOR CONTROLLING BIDIRECTIONAL POWER CONVERTER
Document Type and Number:
Japanese Patent JP2020080620
Kind Code:
A
Abstract:
To provide a technique for suppressing reflux current flowing between sub-circuits in a bidirectional power converter with which a plurality of sub-circuits are connected in parallel.SOLUTION: A voltage converter comprises a first terminal, a second terminal, a main reactor, a plurality of sub-circuits and a controller. Each sub-circuit includes an upper switching element and a lower switching element which are connected in series, two diodes, and a sub-reactor. The controller sequentially controls the plurality of sub-circuits. The controller turns the upper switching element on and off after turning the lower switching element of each sub-circuit on and off while current flows from the first terminal to the second terminal. The controller turns the lower switching element on and off after turning the upper switching element of each sub-circuit on and off while the current flows from the second terminal to the first terminal.SELECTED DRAWING: Figure 1
