基于交错并联PFC的移动DR充电机的研究

摘要

设计了一款用于移动DR（Digital Radiography）的车载集成充电机，为了满足移动DR大功率和低纹波的充电要求，在Boost PFC的设计中引入了交错并联技术。同时，为了实现移动DR的小型化和轻量化，将两路充电模块集成在一起。重点研究了Boost变换器电压、电流双闭环控制回路的设计方法。最后，saber仿真验证了所提充电系统和控制方案的有效性和正确性。%An interated on-board charger using in the mobile Digital Radiography is designed in this paper.Focusing on the design method of voltage and current closed loop control circuit of the Boost converter.Final y the simulation results of saber show the effectiveness and validity of the proposed charging system and control scheme.
