The wide-scale adoption and accelerated growth of electric vehicle (EV) use increasing demand for faster charging necessitate the research development power electronic converters to achieve high-power, compact, reliable EV solutions. Although fast concept is often associated with off-board DC chargers, importance on-board AC undeniable battery capacities. This article comprehensively reviews ga...

Energy storage plays a fundamental role in balancing the power fluctuations induced by distributed generation of renewable energy sources. In this scenario, electric vehicles can strongly contribute to exchange with grid through their on-board batteries. When vehicle is parked, battery be discharged, injecting active into grid, provided that its state charge will restored before utilization. Th...

This paper deals with the design, tuning and implementation of a digital controller for an all-Si electric vehicle (EV) on-board battery charger operated in discontinuous conduction mode (DCM). consists two cascaded conversion stages: front-end power factor corrector (PFC) interleaved legs isolated phase-shifted full bridge DC/DC converter. Both stages operate DCM over complete charging range, ...

With regard to incompatible and low efficiency of lithium-ion batteries, nickel metal hydride batteries and nickel-chrome charger, a generalized smart charger is designed in this paper, which adopts single chip control circuit to make battery charge intelligentize, using on-chip integrated 10-bit A/D converter and 8-bit pulse width modulation (PWM) output, to ensure that the charger with a high...

Recently, the integrated On-Board Charger (OBC) combining an OBC converter with a Low-Voltage DC/DC Converter (LDC) has been considered to reduce size, weight and cost of DC-DC converters in EV system. This paper proposes new V2G (Vehicle-to-Grid) auxiliary battery charge functions. In proposed converter, is composed bidirectional full-bridge active clamp circuit hybrid LDC Phase-Shift Full-Bri...

Due to the symmetrical structure, consistent working characteristics in forward and reverse operations, good soft-switching characteristics, bidirectional CLLLC resonant converters are widely used electric vehicles other fields. To meet requirements of on-board charger, this paper uses a converter as rear-stage charger. The constant voltage current control operation double-closed-loop operation...

Because the on-board charger (OBC) is installed in electric vehicles (EVs), high power density is regarded as a key technology. Among components of the OBC, inductors occupy more than 30% of the total volume. Thus, it is important to reduce the volume and the weight of inductors while maintaining thermal stability. Discontinuous conduction mode (DCM) can satisfy these requirements; however, onl...
