Isolated DC-DC Converter Fed DC Motor for Bidirectional Electric Vehicular Application

摘要

In this paper an isolated dc-dc converter fed dc motor traction drive system for Bidirectional Electric Vehicular applications are designed. In conventional dc-dc converter there is no segregation between input and output. An Isolated dc-dc converter i.e Dual Active Bridge Converter (DABC) having a transformer which segregate input and output side. This isolation can bear anything from a few hundred volts to numerous thousand volts. At the same time transformer step-up and stepdown the voltage level. Sinusoidal-pulse-width-modulation (SPWM) technique is cast-off for triggering the switches. An equivalent proposed model is simulated and verified through MATLAB/Simulink.
