Practical control for improving power density and efficiency of the BLDC generator Academic Article uri icon


  • This paper presents an advanced control technique for maximizing power density and efficiency of the brushless dc generator by using a linear tracking method and also suggests a sub-optimal control method in practical applications. 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 standalone generator. Conventional rectification methods cannot achieve the maximum power possible because of a nonoptimal current waveform. The optimal control scheme to maximize power density and minimize machine size and weight in a nonsinusoidal power supply system has been derived, incorporated in a control system, and verified by simulation and experimental work. A new simple algebraic method has been proposed to accomplish the proposed control without a fast Fourier transform which is time consuming and complicated. 2005 IEEE.
