| Summary: | Improving the energy efficiency of vehicles is an essential feature of scientific and technical progress. One means of increasing the energy efficiency of transport is the introduction of electric drive with multiphase induction motors. At the same time multiphase motors are fed by multiphase frequency converters based on voltage source inverters. The number and operating mode of power switches in multiphase frequency converters may differ from the traditionally accepted in the three-phase converter. The article presents a comparative assessment of losses in three phase and 79-phase frequency converters based on the calculation of static and dynamic losses in the switches of voltage source inverters, the output voltage of which is formed under the law of sinusoidal pulse width modulation and the basic law of switching |
