Abstract

The complete control circuit of a simple resonant DC link (RDCL) inverter with sinewave PWM is presented. The sine and triangular waveforms for deriving the PWM control signals are obtained using waveform generating ICs. The different waveforms obtained on an experimental RDCL inverter along with the frequency spectra are presented. The control circuit first developed for a single-phase inverter is later extended to a three-phase inverter
