Our implementation of PWM modulator is close to [9]. We did not implement compensated dead-time generators (this task will be our next step). Principle of generating sine wave is almost the same, i.e. counter plus PROM sinus lookup table. Optionally, we can replace PROM based sinus generating with CORDIC algorithm (see [10]). Proportional-summation controller can be imple- mented in different ways (e.g. [11]). We implemented simple PS controller only because we needed to com- pare it with DSP based solution.
