Energy saving becomes more and more important. Therefore different improvements have been made in motor design, electronic devices and software in order to increase the overall efficiency of electronic motor drives. Permanent Magnet Synchronous Motors (PMSM) are widely used in different applications requiring high precision and speed control. Using an inverter stage to create the 3-phase sinusoidal waveform currents causes losses in the switches. The aim of this project is to investigate a possible switching loss reduction in the inverter stage. Therefore a hysteresis current controller has to be realized to finally implement the switching loss reduction method in the software. Measurements of the efficiency gain and the current harmonics will have to be carefully analyzed and compared.
