Abstract [en]
This study focuses on analyzing and optimizing LC filter components for the triangular current mode (TCM)-based zero voltage switching (ZVS) inverter. The integration of ZVS and TCM control techniques in TCM-based ZVS two-level three-phase inverters significantly reduces switching losses, enhances overall system efficiency and power density, and mitigates electromagnetic interference (EMI) issues. An LC filter is essential for operating the inverter in TCM-based ZVS mode, ensuring soft switching throughout. Optimized LC filters play a crucial role by providing ZVS at turn-on and turn-off, enhancing motor efficiency by achieving sinusoidal waveforms and minimizing harmonics. Additionally, the design increases copper space in motor winding slots, enabling lower temperature operation, extended lifespan, and reduced reliance on cooling systems. Performance analysis, including output waveform examination, fast fourier transform (FFT), total harmonic distortion (THD) evaluation, and EMI highlights the superior effectiveness of this LC filter-optimized TCM-based ZVS inverter configuration over conventional hard-switched inverters.
