Abstract
The invention provides an apparatus for bi-directional power conversion between a DC circuit and an AC circuit, which inexpensively and simply suppresses generation losses of elements and reduces heat generation, wherein a voltage obtained by dividing the U-phase voltage Vu is compared with a voltage obtained by dividing the voltage vpn of a DC circuit by a comparator CP, and the MOSFET UFETh is turned on at the output timing thereof, and a voltage obtained by dividing the V-phase voltage Vv is compared with a voltage obtained by dividing the voltage Vpn of a DC circuit by a comparator CP, and the MOSFET UFETh is turned off at the output timing thereof.
