Sinusoidal pulse width modulation (SPWM) technology is widely used in power electronic devices with voltage source inverter circuit as the core. How to generate SPWM pulse sequence and its implementation method are the key to PWM technology. Using analog comparison method, the triangular carrier and the sine modulated wave are compared to generate SPWM pulse; using digital algorithm and timing logic, SPWM pulse can also be generated [5]. At present, there are many microprocessor chips (such as 80C196MC, TMS320F240, etc.) that integrate digital PWM generation circuits [3]. The analog method is simple and intuitive, but it is inconvenient to integrate with digital control and it is difficult to meet complex requirements.
