A power control apparatus includes an inverter giving a rectangular waveform drive signal to an induction motor, an inverter voltage controlling section controlling an output voltage of the inverter, a converter boosting a voltage supplied to the inverter, a converter voltage controlling section controlling an output voltage of the converter, and a control signal generating section that controls the inverter voltage controlling section in a low-rotational speed region and controls the converter voltage controlling section in a high-rotational speed regio...
What is claimed is: 1. A power control apparatus for a motor-equipped turbo charger, comprising: a converter which receives a direct current voltage and boosts the direct current voltage to a boosted voltage; an inverter which receives the boosted voltage, generates a waveform drive signal of an output voltage from the boosted voltage, and gives the waveform drive signal to an induction motor to drive a rotary shaft of the turbo charger, the waveform drive signal having a waveform corresponding to a rotational speed of said rotary shaft driven by said i...
