    • A compressor terminal fault interruption method and interrupter for disconnecting power to a compressor terminal (20, 28) when terminal venting failure is imminent including a current sensing circuit (104) for sensing current provided to the terminal by a power source and outputting a sensed signal representing the current provided to the terminal and a control circuit (106). The control circuit includes a first circuit (102, 108) for outputting a reference signal representing input current much higher than locked rotor current, a second circuit (106) connected to the current sensing circuit and the first circuit for comparing the sensed signal to the reference signal, and a third circuit (RY1) connected to the second circuit for disconnecting power to the terminal when the sensed signal exceeds the reference signal, thereby preventing excessive current from reaching the compressor terminal (20, 28).

    • An electric compressor controller includes a compressor that compresses refrigerant of an air conditioning system; a motor that drives the compressor; an inverter that selectively control switching elements based on PWM pulse signals to supply drive power to the motor and heats the refrigerant by heat generated due to switching of the switching elements during a heating operation; temperature detectors each detects junction temperature of each of the switching elements; a drive controller that supplies the pulse signals to the inverter to control the inverter; and a slope varying unit that variably controls precipitous degree of rising/falling slope waveforms of the pulse signals based on the junction temperature detected by the temperature detectors. According to the electric compressor controller, efficiency for heating refrigerant is improved, so that its own heating ability is improved.
