Maximum power throughput in the multiphase brushless DG generator
Additional Document Info
An advanced control technique for maximum power throughput of the multiphase brushless DC (BLDC) generator is presented. In a generator of given rating the weight and size of the system affect the fuel consumption of the generation system directly, especially in vehicle applications. Therefore maximum power density is one of the most important issues in a stand-alone power generation system. A BLDC generator itself has high power density from the machine point of view and additional increases by special control means can be expected. Conventional rectification methods cannot achieve the maximum power possible because of nonoptimal current waveforms. An optimal control scheme to maximise power density and minimise machine size and weight in a multiphase, nonsinusoidal power supply system is proposed, incorporated into a control system, and verified by simulation and experimental work.
