“…Different configurations of bidirectional onboard chargers for four quadrant operation analyzed by incorporating regenerating braking control in the chargers to determine the driving range of the vehicle [5]. DQ current control technique is explained in [6] for a high power density Silicon Carbide (SiC) based bidirectional converter. The harmonics in the AC input current due to the clamp circuit are eliminated in that paper.…”

Extensive research has been ongoing in the field of Electric Vehicle (EV) chargers. This article addresses transfer of electric power from the grid to EV and from an EV to grid, a configuration of a single-phase charger system consists of bidirectional AC-DC converter integrated with bidirectional DC-DC converter. An artificial neural network (ANN) controller is employed for controlling the charging current and voltage. ANN model produces the required duty cycle to feed the maximum power under both Grid to Vehicle(G2V) mode and Vehicle to Grid (V2G) mode. The ANN is trained for the measured battery voltages and battery current to estimate the bidirectional converter's duty cycle. The implementation of the neural network is presented in this study, and simulation results are accomplished using Matlab/Simulink. The simulation findings support the effectiveness of the suggested control technique as well as its practicality. A comparative study is made to show the enhanced performance of the proposed controller than the conventional Proportional-Integral (PI) controller.

Single phase electric vehicle battery charging con verters are bulky due to electrolytic capacitors. These capacitors are used to reduce the voltage ripple in the dc bus. These electrolytic capacitors occupy significant volume and suffer from reliability issues. The required capacitance can be greatly reduced by rejecting the ripple current in the dc bus. The ripple current in the dc bus is rejected at the cost of an additional half bridge inverter. The half-bridge inverter injects a current out of phase in reference to the dc bus ripple current. The current is injected by applying a voltage across an energy storage element (Inductor). The voltage across the energy storage element is controlled by the dutycyle of the half-bridge. A mathematical relationship between the voltage applied across the energy storage element and the ripple current in the dc bus is derived. Analysis of the ripple current rejection is performed on a Dual Active Bridge (DAB) based SiC single phase AC-DC converter capable of sinking or sourcing real and reactive power. Simulation results are presented verifying ripple current rejection in the dc bus for various operating conditions. Average modeling of the inverter leg currents over a switching cycle is also presented to highlight distinct inverter leg current profiles.
