摘要： PROBLEM TO BE SOLVED: To abate inverter loss in a motor-driven compressor and reduce the risk of electric leakage.SOLUTION: An inverter 27 includes a motor drive circuit 28 and a main control computer C1 for controlling the motor drive circuit 28. When a startup command is inputted, the main control computer C1 performs three-phase modulation control and calculates a discharge amount Qx of liquid refrigerant discharged from inside a motor housing 18 since the time point of start of the three-phase modulation control. When the calculated discharge amount Qx of a liquid refrigerant is less than a preset reference amount Qo, the main control computer C1 continues the three-phase modulation control. When the calculated discharge amount Qx of liquid refrigerant is equal to or larger than the preset reference amount Qo, the main control computer C1 switches from the three-phase modulation control to two-phase modulation control.

摘要： PROBLEM TO BE SOLVED: To eliminate the need of adding an excess circuit for discharging a capacitor after a cut-off from a high-voltage battery, and to set a voltage applied to an input stage at a fixed value or below within the fixed time by reducing the capacity of the capacitor.

The drive signal is generated on the basis of the triangular reference waves of a frequency set in response to the capacity of the capacitor 14 setting the voltage applied at the input stage of the inverter device 1 at the fixed value or below within the fixed time and three command values for switching on-off IGBTs corresponding to residual two phases respectively without switching on-off the IGBT corresponding to one phase of three phases.

摘要： PROBLEM TO BE SOLVED: To provide a variable gain amplifier circuit including a parallel variable gain amplifier suppressing variations when a total gain is maximum.
SOLUTION: The variable gain amplifier circuit 1 of the present invention comprises: a parallel variable gain amplifier 20; and a bias generation means 200. The parallel variable gain amplifier 20 includes: a fixed gain differential amplifier 22 which operates with a fixed bias voltage; and a variable gain differential amplifier 24 which is connected in parallel with the fixed gain differential amplifier and gives a gain in proportion with a given variable bias voltage. The bias generation means 200 includes a variable bias circuit 300 for outputting a variable bias voltage which changes with a negative inclination with respect to a given control voltage. A gain of the parallel variable gain amplifier becomes equal with a difference subtracting a variable gain of the variable gain differential amplifier from a fixed gain of the fixed gain differential amplifier, and when the gain of the parallel variable gain amplifier becomes maximum, the gain is equal to the fixed gain.
