| Abstract |
This paper compares space-vector modulation strategies for a standard and a component minimized VSI-inverter where the input is a single phase rectifier. Two component minimized systems are compared with a traditional inverter with six transistors. Space vector modulation strategies are proposed for the three inverters. The modulation strategies are explained and a comparison is done both by simulation and measurement. A detailed description of the implementation is done. It is concluded that a component minimized VSI-inverter can almost get the same performance as a traditional VSI-inverter if the DC-link voltage can be controlled between the input line voltage and twice the input line voltage and the switching frequency is increased by a factor of two. Otherwise the component minimized inverter has a poorer characteristic, but at least two active power components are saved. |
