低电压纹波单相电驱重构型车载充电机研究
Single-phase Electric Drive Reconstructed Onboard Charger with Low Voltage Ripple
摘要
Abstract
Single-phase charging systems usually face the problem of secondary power pulsation.To solve this problem,a single-phase electric drive reconstructed onboard charger(EDROC)system with low voltage ripple is proposed,in which a Buck/Boost active filter is placed in parallel on the output side of a traditional single-phase EDROC system to absorb or compensate the secondary power pulsation,thereby obviously reducing the output voltage ripple of the charging system.First,the topology,working principle and secondary power pulsation generation mechanism of the single-phase EDROC system are analyzed.Second,a single-phase EDROC system with low voltage ripple is put forward by combing the Buck/Boost active filter.Meanwhile,the topology,working principle,and selection of inductors and capacitors of the Buck/Boost active filter are analyzed in detail.Third,a control strategy for the proposed EDROC system is designed.Finally,a 200 W experimental prototype was designed,and experimental results verified the feasibility of the proposed charger.关键词
