1. A matrix converter comprising:
- a plurality of bidirectional switches that are disposed between an alternating current (AC) power source and an AC load; and
a controller that controls the bidirectional switches to directly convert an input power input from the AC power source into an output power to be output to the AC load, whereinthe controller includesan output voltage reference generator that generates an output voltage reference defining an output voltage to be output to the AC load,a corrector that corrects the output voltage reference based on an oscillation component of an input current and/or an input voltage input from the AC power source, anda switch driver that controls the bidirectional switches based on the output voltage reference corrected by the corrector.

Abstract
A matrix converter according to an embodiment includes a plurality of bidirectional switches disposed between an AC power source and an AC load, and a controller that controls the bidirectional switches. The controller corrects an output voltage reference based on an oscillation component of an input current and/or an input voltage from the AC power source.

11. A method for controlling a matrix converter, the method comprising:
-
generating an output voltage reference defining an output voltage to be output to an AC load; correcting the output voltage reference based on any one of or both of an oscillation component of an input current and an input voltage input from an AC power source; and controlling a plurality of bidirectional switches, which are disposed between the AC power source and the AC load, based on the corrected output voltage reference.
