POWER SUPPLY CIRCUIT, MOTOR DRIVE CIRCUIT EQUIPPED WITH SAME, AND REFRIGERATION APPLIANCE EQUIPPED WITH POWER SUPPLY CIRCUIT OR MOTOR DRIVE CIRCUIT

摘要

In order to restrain damage of a component due to rush current, a main relay (87) in a power source circuit (20) is not turned on and does not conduct a power source line even when a heat source microcomputer (42) is activated with a capacitor (22) not sufficiently charged. This configuration avoids start of charging the capacitor (22) without current limitation, to restrain damage of the component due to rush current.
