摘要
逆变式煤电钻电源的输入电压为三相交流660 V,输出为三相交流127 V,通过全桥移相DC-DC变换和三相逆变来实现这个变换。采用MICROCHIP公司的DSPic30F3011 DSP控制器的输出比较模块(OC)控制全桥移相和电机控制PWM模块控制三相逆变。
The inverter power of drill coal whose input voltage is 660 V three - phase AC and output voltage is 127 V three - phase AC, we use phase - shifted full - bridge DC - DC conversion and three - phase inverter to achieve this transformation. We choose DSPic30F3011 DSP controller module of MICROCHIP. This paper in- troduces its usage of output compare （OC） to control phase - shifted full - bridge and PWM motor control module to control three- phase inverter.
