Abstract:

Due to the existence of high current harmonics caused by the rectifier in the novel open-winding permanent magnet generation system with the inverter-rectifier topology. This paper presented the analysis of the causes and components of the current harmonics. The composition of the voltage space vector diagram of the rectifier-inverter were given based on the current state. In order to compensate the vector of the non-linear rectifier, a novel control algorithm based on the voltage vector of the rectifier was proposed to verify the high efficiency and feasibility of the proposed generation system.

Key words: Open-winding permanent magnet generation system, inverter-rectifier, current harmonics, voltage vector of the rectifier
