| Abstract: | The frequency-conversing and speed-govering system that can output high-precision three-phase Sinusoidal Pulse Width Moduktion waveform by using Compare of Event Manager Module in Digital Signal Processor (TMS320LF2407) and handling Regular Sampling are analyzed and designed . Therefore, SPWM control of Inverter is realized. This system take full use of Digital Signal Processor that possesses high-integrative function, digitization, high-speed operation and plenty external device resourse in slice. The system structure and the method for designing the software are introduced. |
