Abstract:In vehicle-to-grid (V2G) systems, electric vehicles interact with the grid as distributed energy storage systems that offer many potential benefits. As an energy interface between a vehicle and the grid, the bidirectional converter plays a crucial role in their interaction. Its reliability, safety, cost, efficiency, weight, size, harmonics, and other factors are of essential importance for V2G realization, especially for on-board operations. Beyond the common existing topologies for bidirectional chargers, this paper introduces a novel high-power-factor bidirectional single-stage full-bridge (BSS-FBC) topology, which offers advantages in power density, size, weight, cost, efficiency, power quality, dynamic characteristic, reliability, and complexity. Its operational principles and control strategies are presented. Harmonic analysis on the basis of double-Fourier integral is performed with detailed comparison of line current harmonic characteristics between the BSS-FBC topology and unipolar/bipolar controlled single-phase pulse width modulation (PWM) converters. A dynamic model of the topology is derived, its dynamic behavior analyzed, and its compensator design method developed. Simulation and experimental results are employed to verify the design and analysis. Design considerations for the key parameters are discussed. A 3.3 kW prototype is developed for this topology and validated in its vehicle applications. The results demonstrate clearly the benefits and advantages of the new topology.

“…However, considering that a great amount of power is delivered in such a short time, it is possible identify advantages and disadvantages when this method is compared with slow battery chargers [10]. Taking into account that the required energy is provided from the power grid it is expected that the power quality issues are not neglected [11][12] [13]. The EV battery charging process requires the conversion of ac voltage from the power grid to a dc voltage to charge the batteries.…”

This paper presents a three-phase three-level fast battery charger for electric vehicles (EVs) based in a current-source converter (CSC). Compared with the traditional voltage-source converters used for fast battery chargers, the CSC can be seen as a natural buck-type converter, i.e., the output voltage can assume a wide range of values, which varies between zero and the maximum instantaneous value of the power grid phase-to-phase voltage. Moreover, using the CSC it is not necessary to use a dc-dc back-end converter in the battery side, and it is also possible to control the grid current in order to obtain a sinusoidal waveform, and in phase with the power grid voltage (unitary power factor). Along the paper is described in detail the proposed CSC for EVs fast battery charging systems: the circuit topology, the power control theory, the current control strategy and the grid synchronization algorithm. Several simulation results of the EV fast battery charger operating with a maximum power of 50 kW are presented.

“…In [18], a unidirectional auxiliary power conditioning pass is added to a two-stage non isolated vehicular utility interface. The shortcomings are that the auxiliary mode needs reconfiguring the power converter and there is no pass to transfer energy from the low voltage battery to the high voltage battery.…”

In recent years, there has been a trend on developing the grid connected vehicles. The futuristic grid connected vehicles need onboard bidirectional power converters to charge their batteries and return the power to the grid during the Vehicle to Grid (V2G) operating mode. This paper extends the functionality of this onboard power converter to a multiport power converter that integrates all the vehicle's sources and loads into a vehicular integrated power system. This highly integrated power system has unique characteristics and brings new functionalities into the vehicle. The general concept of the vehicular integrated power system is introduced in this paper. This concept is realized through the multiport series ac link power converter topology. The fundamental operations are demonstrated through the developed modular experimental setup.
