Comparison of SVPWM Techniques Under Switching Loss Control for Induction Motor Drive With LC Filters

Only precise industrial applications can benefit from the high-frequency performance of variable-speed drives with low switching losses. A five-phase induction motor (FPIM) is connected to a voltage source inverter (VSI) via $LC$ filter (low pass filter) reduce losses in motor. sinusoidal used lower high notation="LaTeX">$dv/dt$ at terminals. However, sustained resonant frequency oscillations destabilize closed-loop control FPIM drive certain operational points. This paper presents and analyzes variety SVPWM techniques, both continuous discontinuous. It also possible optimize two-level VSI fed using an improved current ripple prediction method. Auxiliary circuits sensors are not necessary this system, making it more stable. Simulated experimental results evaluate stability under conditions.
