Operational Modes

The paper deals with modeling and simulation of chosen operational modes of HEV vehicle with direct AC/AC transfer and five-phase IM traction motors. Such configuration yields smaller voltage drops com-pared with the serial AC/DC/AC converter and five-phase machines offer some inherent advantages over their three-phase counterparts. The advantages include reduced electromagnetic torque pulsation and also noise characteristics of the five-phase drives are better when compared with the three-phase ones. Charging and braking regimes were chosen as possible operational modes for modeling and analyses. The result of the simulation. carried out with using of Matlab/Simulink are given in the paper.

Torque Analysis

The process of starting a three-phase induction motor consumes a very largecurrent from the power grid, which can cause voltage drops and damage the coilinsulators due to the heat generated. However, this has been overcome by using severalstarting methods including star-delta starter, starter with autotransformer, soft starter,and drive frequency or better known as VFD or VSD. In conventional soft starters, asmall reduction in voltage results in a sizable drop in electromagnetic torque. This cancause a motor with a certain load to fail to start. In this research, a three-phase inductionmotor soft starter modeling will be carried out using the method of setting the sourcevoltage and frequency, designed to overcome the low electromagnetic torque generatedby conventional soft starters. The modeling of the soft starter with thyristor control isexpected to produce high and stable electromagnetic torque. So that the soft starter withthyristor control can be a solution for conventional soft starters.

Vector Control System

In the AC control system, vector control theory is very popular as it makes the AC motor achieve the performance as perfect as DC motor [1]. In the paper, the vector control theory is briefly introduced, and then a vector control system model is builded in the matlab/simulink, and the SVPWM technique is adopted. The results show that the improved vector control sytem of PMSM has a excellent performance.
