Abstract :
A new on-board charger for plug-in hybrid electric vehicles (PHEVs) is presented. It has a cascade structure of a high-frequency resonant converter with a variable structure according to the line voltage for electrical isolation and a boost converter for charge control and harmonic regulation of input current. This structure uses small link capacitors so that high-voltage electrolytic capacitors prohibited in automotive applications can be removed. The feasibility of the proposed charger has been verified with a 3 kW prototype.
