  • Power source control circuit
    Patent number: 11374524
    Abstract: In order to restrain damage of a component due to rush current, a main relay in a power source circuit is not turned on and does not conduct a power source line even when a heat source microcomputer is activated with a capacitor not sufficiently charged. This configuration avoids start of charging the capacitor without current limitation, to restrain damage of the component due to rush current.
    Type: Grant
    Filed: October 9, 2019
    Date of Patent: June 28, 2022
    Assignee: DAIKIN INDUSTRIES, LTD.
    Inventors: Toshiaki Sato, Toshio Yabuki, Narushige Ueda
