Windowing Effect on Electromagnetic Interference and Efficiency at Using Pulse Width Modulation Techniques

摘要

The PWM technique, which is used for voltage inverters of traction drives is analyzed. To decrease the higher harmonics level, various finite-impulse response (FIR) filters are considered. Obviously, that changes the efficiency of output signals. Therefore electromagnetic interferences and efficiencies are examined. The electromagnetic interferences and efficiencies are examined using numerical simulations.
