CONSTITUTION: A pump system comprises a pump, an AC motor, a converter, a capacitor filter, an inverter, a V / f PWM controller, and a main controller. The convertor converts DC power into AV power. The capacitor filter filters the converted AC power into smooth state. The inverter converts the filtered AC power to DC power. The V / f PWM controller applies switching voltage to the semiconductor switching element of an inverter. The main controller outputs voltage order signals and frequency order signals to the V / f PWM controller for various performances.
