| Abstract: | The system of the evaporating fan of automobile air-conditioner and contravariant device is a kind of mechatronics system products. The contravariant device is based on sinusoidal pulse width modulation(SPWM) technology. The main circuit adopts the threephase bipolarity contravariant bridge circuit composed of power bipolar-transistor. The control circuit adopts digital integrated circuit. The device can realize to change DC voltage into the threephase sinusoidal voltage of variable frequency and variable value inter automobile and drive the threephase AC motor. |
