    摘要: Provided is a matrix converter including a power converter, a commutation controller, and a compensator. The power converter includes a plurality of bidirectional switches. The commutation controller performs one of a three-step commutation operation and a four-step commutation operation by the bidirectional switches as a switch source and the bidirectional switches as a switch destination when an input terminal to be connected to an output terminal is switched by on/off control of the bidirectional switches. The compensator compensates for an output voltage error generated when the input terminal to be connected to the output terminal is switched, based on a potential difference before and after the switching of the input terminal to be connected to the output terminal, an output current of the output terminal, and capacitance between input and output terminals of unidirectional switches.

    摘要: A power converter according to embodiments includes a boost circuit, a single-phase inverter, a current controller, and a power conversion controller. The current controller generates a voltage reference based on a difference between current output from the single-phase inverter and a current reference. The power conversion controller controls the single-phase inverter to generate a first portion of the AC voltage, and controls the boost circuit to generate a second portion of the AC voltage. The first portion corresponds to the voltage reference of which an absolute value is smaller than the voltage of the DC power supply. The second portion corresponds to the voltage reference of which an absolute value is greater than the voltage of the DC power supply.
