METHOD FOR CONTROLLING OF INVERTER

摘要

PURPOSE: An inverter control method is provided to prevent contact damage of a relay for power control by reducing the number of contact control times of a relay controlled for power on/off. CONSTITUTION: Whether the outside temperature is greater than a predetermined temperature or not is detected(S101). If the outside temperature is greater than the predetermined temperature, uninterrupted power is supplied to an inverter driver module unit(S102). If the outside temperature is smaller than the predetermined temperature, whether internal temperature of a storage room is an operating condition of a compressor or not is detected(S103). If the internal temperature of a storage room is not an operating condition of a compressor, power of the inverter driver module unit is turned off(S104). If the internal temperature of a storage room is an operating condition of a compressor, power of the inverter driver module unit is turned on(S105).
