摘要
根据一种新型PWM波形调制方法,设计了基于FPGA的新型PWM三相波形发生器集成电路,该IC适用于三相异步电机的变频驱动,具有较普通的SPWM谐波小,电压利用率高的特点,并进行了仿真实验,符合设计要求.
New PWM 3- phase wave generator IC based on FPGA is designed. This IC can be used for the inverter driver of asynchronous motor. It has smaller harmonic and higher utility ratio of voltage than SPWM. From the simulation and lab, it can work well.
