Title:
The optimization method of an electric power unit, an inspection device, and an electric power unit
Document Type and Number:
Japanese Patent JP6080326
Kind Code:
B2
Abstract:
This power-supply device (1) is provided with the following: a storage unit (30) that stores first dead times for switching elements (Q5 and Q6) that perform synchronous rectification; a detection unit (surge-voltage detection circuit (63)) that detects surge voltages across the switching elements; a transmission unit (104) that outputs information indicating a surge voltage detected by the detection unit; an acquisition unit (102) that acquires information on second dead times set on the basis of the surge-voltage-indicating information; a replacement unit (103) that replaces the first dead times stored in the storage unit with the second dead times acquired by the acquisition unit; and a control unit (101) that controls the switching elements in accordance with the second dead times stored in the storage unit.
