ELECTRIC POWER SOURCE DEVICE, CAR PROVIDED WITH SAME, CONTROL METHOD OF ELECTRIC POWER SOURCE DEVICE AND COMPUTER READABLE RECORDING MEDIUM THAT RECORDS PROGRAM FOR COMPUTER TO EXECUTE THE CONTROL METHOD

摘要

When request power required of a power supply device (1) by a driving force generation unit (3) is close to zero, a converter ECU (2) controls first and second converters (8-1, 8-2) to prohibit respective amounts of current passage in the first and second converters (8-1, 8-2) from simultaneously becoming close to zero. That is, when the request power is close to zero, the converter ECU (2) performs voltage control of the first converter (8-1) and sets an electric power control value for the second converter (8-2) subjected to current control (electric power control) to a nonzero value, such that electric power is supplied and received between the first and second converters (8-1, 8-2).
