In this paper, a new current control algorithm is proposed for four-switch three-phase brushless DC (BLOC) motor drives, which are suitable for low cost applications A current reference generation scheme is developed and Implemented to obtain high performance characteristics in the four-switch system, such as small torque ripple and fast dynamic speed/torque response Moreover, the proposed scheme can successfully eliminate the torque ripple during commutations, so that It can be expected that the four-switch system can be much more practically applied for the industrial application areas

In this paper, we propose a new diagnosis method of DC/DC converter aging. The method is based on parasitic resister change with aging process we apply to on-line diagnosis of DC/DC converter because of observing not a device but a system We present the mathematical analysis and experimental study<br/>
