Power converter
Abstract:
A control unit determines a polarity of an actual voltage value of an AC power supply if it is either positive or negative based on a detection voltage thereof detected by the voltage detector. The control unit alternately actuates a set of a first switch and a fourth switch and another set of the second switch and a third switch each time when it is determined that the polarity of the actual voltage value of the AC power supply changes. A second reactor is disposed at at least one of first and second positions. The first position is located between a first AC side terminal and a connection point located between the first switch and the second switch. The second position is located between a second AC side terminal and a connection point located between the third switch and the fourth switch.
