Power density maximization of the brushless DC generator

This paper presents an advanced control technique for power density maximization of the brushless DC (BLDC) generator by using linear tracking method. In a generator of given rating, the weight and size of the system affect the fuel consumption directly therefore, power density is one of the most important issues in a stand-alone generator. The optimal current waveform for maximizing power density and minimizing machine size and weight in a nonsinusoidal power supply system has been proposed and verified by simulation and experiment. Also, a new simple algebraic method has been proposed to accomplish the proposed control without a FFT which is time consuming and complicated.
