abstract
This paper presents an advanced control technique for maximum power throughput of the multiphase Brushless DC (BLDC) generator of given design. In a generator of given rating, the weight and size of the system affect the fuel consumption directly. Therefore, maximum power density is one of the most important issues in a stand-alone generator. BLDC generator has high power density in the machine point of view and additional increases by control means can be expected. Conventional rectification methods cannot achieve the maximum power possible because of non-optimal current waveforms. The optimal control scheme to maximize power density and minimize machine size and weight in a multiphase, nonsinusoidal power supply system has been derived, incorporated in a control system, and verified by simulation and experimental work. 2004 IEEE.
