Wireless charger for Electric Vehicles (EVs) is an off-line application and it needs power factor correction (PFC) function, which usually consists of a front-end boost PFC and a cascaded DC/DC converter. Recently, Z-source resonant converter (ZSRC), a single-stage solution with low cost and high efficiency, was proposed for EV wireless charger. Combining with the Z-source network, the control scheme...
An effective output voltage regulation method using harmonic burst mode control strategy is presented. By using this strategy, the operating performance of the full-bridge series resonant dc-dc converter (SRC) applied to electric vehicle (EV) battery charging is improved. The proposed control strategy not only performs load regulation, but it also achieves soft switch both at turn-on and turn-off...
This paper presents a new zero current switching (ZCS) technique for a family of switched-capacitor dc-dc converters. Compared to the traditional ZCS switched-capacitor dc-dc converters by inserting a magnetic core in the circuit, these new ZCS switched-capacitor dc-dc converters employ the stray inductance present in the circuit as the resonant inductor and provide soft switching for the devices...
