Power converter

A power converter comprising:

• a first reactor;
• a first AC side terminal connectable to an AC power supply;
• a second AC side terminal connectable to the AC power supply;
• a first DC side terminal connectable to a DC power supply;
• a second DC side terminal connectable to the DC power supply;
• a full bridge circuit disposed between each of the first and second AC side terminals and the first reactor,
• the full bridge circuit having a first serial coupling composed of a series of a first switch and a second switch,
• the full bridge circuit having a second serial coupling composed of a series of a third switch and a fourth switch, the first and second serial connection bodies being connected in parallel to each other,
• the full bridge circuit having four diodes connected to the first to fourth switches in reverse parallel to the first to fourth switches, respectively,
• the full bridge circuit having a first connection point located between the first switch and the second switch in a wiring, the first connection point being connected to the first AC side terminal,
• the full bridge circuit having a second connection point located between the third switch and the fourth switch in the wiring, the second connection point being connected to the second AC side terminal;
• a voltage detector to detect a voltage of the AC power supply;
• a control unit to perform at least one of first and second functions,
• the control unit converting an AC voltage supplied from the AC power supply through each of the first and second AC side terminals into a DC voltage and outputting a conversion result through each of the first and second DC side terminals as the first function,
• the control unit converting a DC voltage input through each of the first and second DC side terminals into an AC voltage and outputting a conversion result through each of the first and second AC side terminals as the second function,
• the control unit determining if a polarity of an actual voltage value of the AC power supply is either positive or negative based on a detection voltage of the AC power supply detected by the voltage detector,
• the control unit alternately actuating a set of the first switch and the fourth switch and another set of the second switch and the third switch each time when it determines that the polarity of the actual voltage value of the AC power supply changes;
• and
• a second reactor disposed at at least one of first and second positions, the first position being located between the first AC side terminal and the first connection point in a wiring, the second position being located between the second AC side terminal and the second connection point in a wiring, the second reactor suppressing a change in current flowing through the first and second AC side terminals based on an inductance thereof.
