  • Patent number: 8351224
    Abstract: A power conversion apparatus includes a main circuit with switches, and performs power conversion to generate power to a three-phase AC load from a three- or single-phase AC power supply. Some of the switches are configured, using a bidirectional switch including a normally-on device that is turned OFF when a gate circuit is provided with a positive or negative voltage, and a normally-off device that is turned ON when the gate circuit is provided with a positive or negative voltage, to provide only a specific unidirectional current flow when the gate circuit is not activated, and when the gate circuit is activated, provide and control a bidirectional current flow to direct only in an arbitrary unidirectional way. By providing the power conversion apparatus with a capability of directing back, to a load (motor), any power coming therefrom, the conversion apparatus requires no direct-current link capacitor and a diode clamping circuit.
