The document discusses simulation analysis of different harmonic mitigation methods for a three phase rectifier circuit. It analyzes the rectifier circuit without input filtering and with passive input filtering using inductors and capacitors. Input current and output voltage waveforms are presented for various circuit configurations. Key findings include that passive input filtering reduces input current distortion and THD, but adds components that increase costs.
