SPWM based DSP waveform generator
no vote
Application background DSP2812 in the SPWM waveform, has been debugging through, the program written in C language, the more detailed notes Key Technology SPWM (PWM Sinusoidal) method is a relatively mature, the current use of a wide range of pwm. One of the important conclusions of the theory of sampling control is that the impulse is equal and the narrow pulse with different shapes and different shapes are basically the same as that in the process of inertia. SPWM method is based on this conclusion, the PWM waveform which is equivalent to the sine wave and the SPWM wave is the same as the output voltage and the output voltage of the inverter circuit is equal to the frequency and amplitude of the output voltage.
