Abstract
V-phase upper-arm open phase detecting circuit outputs a permission signal to allow U-phase lower-arm MOSFET to be conductive when the V-phase voltage is higher than the positive electrode potential. In response to this permission signal, U-phase lower-arm driver circuit drives U-phase lower-arm MOSFET. V-phase lower-arm open phase detecting circuit outputs a permission signal to allow U-phase upper-arm MOSFET to be conductive when the V-phase voltage is lower than the negative electrode potential. In response to this permission signal, U-phase upper-arm driver circuit drives U-phase upper-arm MOSFET.Thereby, a MOS rectifying device capable of rectifying even when an open phase occurs, a driving method thereof, and a motor vehicle using thereof can be provided.
