Abstract:
1. A power converting device for use with an AC power source, a DC power source, and an AC motor, comprising: a voltage source rectifier that converts alternating current power from the AC power source into direct current power, the voltage source rectifier having an input side and having an output side that is coupled to the DC power source, the voltage source rectifier additionally having upper and lower arm portions with switching elements; first switch means for switchably coupline the AC power source to the input side of the voltage source rectifier; a voltage source inverter that receives direct current power from at least one of the voltage source rectifier and the DC power source and that drives the AC motor, the voltage source inverter having an input side; second switch means for switchably coupling the output side of the voltage source rectifier and the input side of the voltage source inverter; a series circuit that includes at least one reactor and third switch means for switchably coupline the at least one reactor between the input side of the voltage source rectifier and the input side of the voltage source inverter; and control means for selectively chopper controlling at least one of the upper and lower arm portions of the voltage source rectifier.
