1.1 Introduction

Many electric car charging solutions today are as easy as a car-to-grid link, with nothing else in between to tell either building managers or grid operators who charge when and how much electricity. But as electric cars become more popular, the need for building managers to be able to communicate with AC car chargers will grow as companies and residents try to juggle energy demands. Plug-in electric vehicle (EV) power conditioning system consists of an AC/DC boost rectifier accompanied by an independent DC/DC converter to charge a high-voltage battery bank. The front-end converter has PFC controller stage and the charger stage; the PFC stage is to enhance the input current quality received from the power supply and the charger stage is designed to energize the battery bank. Figure 1.1 shows the proposed charger for an EV. For the front-end PFC stage, boost converters with interleaving concept are generally used. In this paper, bridgeless interleaved (BLIL) boost AC/DC [1, 2, 3 and 4] converter is preferred. The main advantages of BLIL boost converter over conventional interleaved topology are increased converter’s efficiency, increased reliability of the system by device paralleling, increased output voltage ripple frequency, decreased voltage and current stresses in the power semiconductor devices, decreased input current ripple, reduced passive components, and EMI filter size. The current ripple at the input side is reduced by interleaving [5], and to ensure it, the gating pulses to the switches are given with a phase shift of 180°. Here, four-channel interleaving inductors are used to reduce the input current ripple, inductor size, and output current ripple.

FIGURE 1.1 Bridgeless AC/DC boost converter with the isolated resonant DC/DC converter.

The popular full bridge topology [6] is chosen as the second-stage DC/DC conversion because it is highly efficient with high power density and reliability. The isolated second stage is based on resonant and PWM topology. In the traditional resonant converters, to achieve zero voltage switching (ZVS) and zero current switching (ZCS) for the power semiconductor devices, a large value of reactive current distribution for wider load variation is required. This results in bulky resonant tank and low power density. To make this possible, auxiliary circuits for commutation have been reported in the literature [7, 8, 9, 10 and 11]. The major drawbacks of the conventional resonant converters are as follows: (i) ZVS for the lagging leg switches that are restricted for large load variations, (ii) immoderate conduction losses in passive intervals due to the circulating currents through the output inductor, and (iii) critical voltage overshoot and oscillation for diodes when the converter is operated at high voltage. Moreover, the numbers of components used in the traditional DC/DC converter are more ...
