Abstract—
In this paper, a phase shifted semi-bridgeless boost power factor corrected converter is proposed for plug in
hybrid electric vehicle battery chargers. The converter features high efficiency at light loads and low lines, which is critical to minimize the charger size, charging time and the amount and cost of electricity drawn from the utility; the component count, which reduces the charger cost; and reduced EMI. The
converter is ideally suited for automotive level I residential charging applications.
A detailed converter description and steady state operation analysis of this converter is presented. Experimental results of\ a prototype boost converter, converting universal AC input voltage to 400 V DC at 3.4 kW are given and the results are compared to an interleaved boost converter to verify the proof of concept, and analytical work reported. The results show a power factor greater than 0.99 from 750 W to 3.4 kW, THD less than 5% from half load to full load and a peak efficiency of
98.6 % at 240 V input and 1000 W load.
