Modeling and Simulation of Hybrid Electric Vehicle Power Systems
نویسنده
چکیده
Using a top-down design methodology, two levels of hybrid electric vehicle power system are presented in the paper. At the highest abstraction level, a behavior modeling method is used to develop models for 3-phase AC/DC converter and brushless DC motor controller, which reduce the simulation time without compromise of accuracy. At the second level of design, six diodes along with delta-delta and delta-wye transformer are used to simulate the 3-phase, 12-Pulse rectifier. Six switches are used as power devices to simulate the PWM motor controller. DC outputs at different load conditions, motor speed, under-voltage protection, overcurrent protection as well as input current THD (Total Harmonic Distortion) are simulated using Saber's Virtual Prototyping solution. The results of two abstraction levels match well and both of them meet the specifications of the design.
