| Abstract: | Digital PWM wave obtained by CPLD has advantages of convenience, accurate control and in-system programming, endowing the system design with much higher use value. Alternating-direct-alternating circuit is adopted and CPLD is used as logic control device of power IGBT in main circuit of variance-frequency timing system. The realization of PWM wave by CPLD is discussed from viewpoints of hardware and software. It is proved by design and application that this technique can significantly improve the stability and reliability of the system. |
