Abstract
An inverter controlling method is applied in a system comprising a single-phase rectification circuitry and three-phase inverter. The method determines a capacitance of a capacitor connected between output terminals of the single-phase rectification circuitry for allowing an output voltage of the single-phase rectification circuitry to pulsate at twice frequency with respect to a power frequency; controls the three-phase inverter for supplying output voltages or output currents from the three-phase inverter to a motor; and suppresses a current flowing into the capacitor from a power source via the single-phase rectification circuitry.
