摘要
In the battery charging device of the present invention, a U, V, W phase voltage generating circuit detects a voltage signal of a U phase sub-coil of a three-phase alternating current generator, and generates a signal of a triangular wave that is in synchronization with the U phase. Moreover, a first triangular wave is generated in synchronization with a phase from 0° to 180° of the U phase rectangular wave, and a second triangular wave is generated in synchronization with a phase from 180° to 360° of the U phase. In addition, a V phase rectangular wave is generated in which the level is inverted at a voltage point of two thirds the peak voltage of the first triangular wave, and in which the level is inverted at a voltage point of two thirds the peak voltage of the second triangular wave, and a W phase rectangular wave is generated in which the level is inverted at a voltage point of one third the peak voltage of the first triangular wave, and in which the level is inverted at a voltage point of one third the peak voltage of the second triangular wave.
