Abstract : This work proposes a charging system using split phase supply for electrically driven vehicles. The proposed configuration uses a PWM converter and an integrated bidirectional buck-boost converter as a charger which has lesser number of switches than other conventional chargers. Split phase systems will be normally used with unbalanced loads due to which there will be unbalanced source currents existing in the system. The main objective of this work is to reduce the unbalanced currents and also to eliminate the harmonics thereby achieving sinusoidal source currents with unity power factor in the split phase system for which a constant DC voltage control is used. The behavior of the system with the proposed control algorithm is analyzed and validated using MATLAB & Simulink based simulation.
