摘要
PURPOSE: A controller of an inverter, an air conditioner and a washing machine using the same are provided to improve an output torque in a weak field operation by increasing a voltage supplied to the inverter.;CONSTITUTION: An inverter(2) is comprised of an inverter main circuit(21) comprised of an IGBT(Insulated Gate Bipolar Transistor) and a diode, and a gate driver(22). The inverter converts a DC voltage from a DC source(3) into an AC voltage and supplies the AC voltage to a motor(1). A DC current detector(4) detects a DC current inputted to the inverter by using a DC shunt resistor. A DC voltage detector(31) detects the DC voltage applied to the inverter. A controller(5) comprises a current reproduction unit, a PWM generator(7), and a voltage command operator(9).;COPYRIGHT KIPO 2011
