An interior permanent magnet motor is a good option for traction application related to the induction motor and switched reluctance motor because of high mechanical rigidity and low demagnetization risk. the design of this kind of motor is attractive for engineer despise the implementation cost of them in high constant speed power range (CPSR) is high. in this paper using combination of two ideas i.e. non conventional air bridge and segmented permanent magnet a optimal design has been proposed. in this paper non conventional air bridge is used for reducing the permanent magnet volume. the genetic algorithm has been applied to the goal function. simulation results show the good performance of optimal design related the conventional design.

Harmonic pollution of source currents and poor power factor are the main challenges of rectifiers. In this paper using one cycle control strategy, rectifiers can be operated at unity power factor. For performance analysis of this method harmonic injection and unbalanced load applied to the source side considered. Simulation results show that combination of three phase four leg rectifier with one cycle control can be improved power factor and harmonic pollution reduction especially in nonlinear and unbalanced loads in the source side.
