Abstract DC-DC converter is the crucial part that directly affects the operation efficiency of on-board charger. In recent years, researches on PWM soft-switching DC-DC converters have been carried out, and quite a few achievements have been proposed to realize the high-efficiency operation of DC-DC converters during the entire battery charging period. In this paper, the general requirements for DC-DC converter of on-board chargers are specified, and several inherent shortages of conventional primary-side phase-shift full-bridge DC-DC converter are firstly analyzed. Then the research status on PWM soft-switching DC-DC converter of on-board charger is thoroughly reviewed based on the main circuit topologies, gating schemes and control strategies. Finally, the pros and cons of the existing technique schemes are discussed, and future works are pointed out to realize the overall efficiency improvement of DC-DC converters.
