摘　　要：研制了一款适用于750 V牵引系统的有轨电车充电装置,整个装置采用Boost-Buck两级级联方式,为了提高整个充电装置的转换效率,降低整个系统输出的纹波系数,采用两相交错并联的方式,Boost采用电压外环、电流内环双闭环控制,Buck采用恒压/恒流切换控制,同时给出了两侧电感感值的选取方法。在PSCAD中进行模型搭建,通过仿真分析其原理的可行性,同时搭建实验平台验证方案的可行性。A trolley car charging device suitable for 750 V traction system is developed.The whole device adopts Boost-Buck two-stage cascade mode,in order to improve the conversion efficiency of the whole charging device and reduce the ripple coefficient of the whole system output.A two-phase interleaving and parallel connection method is used to control Boost.The double closed loop control of voltage outer loop and current inner loop is used to control Buck.The constant voltage/constant current tangent loop is used to control the Boost.At the same time,the method of selecting the inductance of both sides is given.The model is built in PSCAD,and the feasibility of the principle is analyzed by simulation.At the same time,an experimental platform is built to verify the feasibility of the scheme.
