A vector control method of single phase brushless DC (BLDC) motor is proposed in this paper which can effectively improve system efficiency and reduce the torque ripple. In this paper, a virtual phase current iimag is deduced to construct a pair of orthogonal currents ireal and iimag. With the dq rotating coordinate transformation, and single phase SVPWM modulation, the vector control of single phase...
Abstract-the single phase brushless DC (BLDC) motor is widely used in the automotive air conditioning systems with its high efficiency and low cost. With the EV system demand, higher requirements are put forward in aspects of efficiency, vibration and noise. To obtain high optimal operational performance, a novel vector control mothed of single phase BLDC is proposed based on usual platform. In this...
An improved vector control scheme for an energy feedback power dynamometer is proposed in this paper. The power dynamometer can be operated in both motoring and generating states. In generating mode the dynamometer can feedback the energy with unit power factor. In order to improve the dynamic response, improved vector control scheme is introduced. The torque control method is adopted in the outer-loop...
