Simulation and experimental results are pre-sented for a double-cell series-connected voltage source PWM inverter in single-phase and three-phase configuration. Simula-tion results for a three-phase five-cell inverter are also given. The multilevel SHEPWM method is capable of providing very-high-quality output waveforms.
Abstract— Selective harmonic elimination pulsewidth modu-lation (SHEPWM) method is systematically applied for the first time to multilevel series-connected voltage-source PWM inverters. The method is implemented based on optimization techniques. The optimization starting point is obtained using a phase-shift harmonic suppression approach.
The SHEPWM method presented in offers the same number of control variables as the number of inverter levels. Results given in are only for a five-level inverter allowing up to seven switching angles without taking into account that inverter cells should equally share the output power.
Inverters are essential for converting direct current to alternating current in electric vehicles, relying on pulse width modulation (PWM) for efficiency. This study presents a real-time Selective Harmonic Elimination PWM (SHE-PWM) algorithm using artificial neural networks, validated with the OP5600 RT LAB simulator.
