Title:
BOOSTER CIRCUIT, MOTOR DRIVE MODULE, AND REFRIGERATOR
Document Type and Number:
Japanese Patent JP2014131372
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a booster circuit capable of achieving cost reduction and high efficiency and motor drive module.SOLUTION: The booster circuit includes: a diode rectifier circuit that converts an AC voltage into a DC voltage and a DC-DC converter that isolates an output and an input through an isolation transformer. The input of the DC-DC converter is connected to the DC side of the rectifier circuit, while the negative side of the output is connected with the positive side of the rectifier circuit and an output voltage or an output current of the DC-DC converter is adjusted and thereby a DC voltage obtained by connecting the DC-DC converter with the output of the rectifier circuit in series can be adjusted.
