The actual trend in automotive is to reduce as much as possible pollution caused by motor vehicle emissions. This could be achieved by using electrical propulsion systems which usually contains: electrical machine, three phase voltage source inverter (VSI), voltage supply system. The main problem of the full electric vehicles represents the autonomy due to low energy capacity of batteries. This issue...
A propulsion system for hybrid electric vehicles and electric vehicles contains DC voltage supply, DC link capacitor, three phase voltage source inverter and a three phase AC machine. The key role of the inverter is to convert DC voltage to three AC voltages which commands the motor. The electrical machine is chosen to have the phase voltages in star connection and the common node of the phase voltages...
The control of a three phase AC motor is performed with a three phase inverter. A key role in the correct functioning of the inverter is the used modulation technique. In this paper is proposed a class of modulation algorithms for the three phase inverters which have the advantage of a very simple implementation. The equivalence between a modulation strategy from this class and classical space vector...
