PERFORMANCE OF PARALLEL HYBRID ELECTRIC VEHICLE ELECTRICAL PROPULSION SYSTEM USING DIFFERENT INVERTER CONTROL TECHNOLOGIES

摘要

This paper present application of electrical propulsion system of the Parallel Hybrid Electric Vehicle (PHEV) using three different Pulse width modulation (PWM) techniques and their results compared in terms of THD, DC voltage utilization, transient behavior, and the required execution time applied. The intelligent Fuzzy Logic Control (FLC) is applied to improve the dynamic performance of PHEV. The electrical motor drive is controlled via PWM-voltage source inverter (VSI), using scalar control method and three types of PWM Sinusoidal PWM (SPWM), conventional Space Vector PWM (SVPWM) and carrier-base SVPWM are analyzed. In the other hand the PHEV system modeled and simulated for different roads (straight, clamping, and down inclination roads).Not only that but also under different road cycle’s small federal urban drive (SFUD), and high way (HY). The control algorithm is based on the road cycle and in all it the vehicle is driven at starting with the IM, and the internal combustion engine (ICE) is used mainly in HY road cycle, while the IM is used mainly in the urban-areas to reduce the emissions in it. The hybrid operation is also considered in some parts of the road cycles. The SIMPLEV software program is used to study the vehicle emissions in the different road cycles to ensure that the used control algorithm decreases the vehicle emission in urban areas.
