Five Level Multilevel Inverter with PWM and Nearest level Modulation Techniques ===============================================================
A pulse-width modulated (PWM) and Nearest level modulated single-phase multilevel voltage-source inverter topology is discussed in this video. The use of the alternate phase opposition (PO) carrier disposition multicarrier PWM switching technique for this topology is presented. Inverter switch control signals are derived. A 5-level and a 3-level PWM and nearest level voltage waveform across the load is generated, for high and low modulation indexes respectively. Performance characteristics including total harmonic distortion for a range of operating conditions of the inverter are provided. Theoretical considerations discussed in this video are supported by simulation results. ===============================================================
