  • Method for operating an inverter of an electrical refrigerant compressor making use of DC link electrolyte capacitors
    Patent number: 9825615
    Abstract: A method of operating an inverter including the steps of detecting the temperature of the at least one electrolytic capacitor; selecting at least one of a plurality of switching patterns based on the temperature of the at least one electrolytic capacitor; and generating a ripple current across the at least one electrolytic capacitor by operating the inverter from the at least one of the plurality of switching patterns for preheating of the at least one electrolytic capacitor.
