摘　　要：传统的锂电池化成控制系统造成大量的能源浪费并对电网污染严重。针对此问题,提出了一种能量受控的双向AC/DC变换器,该变换器采用改进的电压型PWM整流器与半桥型双向DC/DC相结合的拓扑结构,以新一代飞思卡尔单片机MPC5604B为核心控制芯片,并运用电压电流双闭环的控制算法,实现能量的双向流动以及锂电池的恒压、恒流充放电功能。通过实验证明该变换器基本可以实现充电时网侧功率因数为1和放电时功率因数为-1。With the rapid development of power for the lithium battery formation, the problem of the formation con-trol system of traditional lithium-ion batteries caused a lot of energy waste and pollution to power network is increas-ingly prominent, and the research of the efficient lithium battery formation equipment is becoming more and more important. In light of this problem, this dissertation proposed a lithium battery formation bidirectional AC/DC con-verter. The converter uses an improved form of voltage type PWM rectifiers and half bridge bidirectional DC/DC to-pology combination, and uses the MPC5604B of the new generation of Freescale microcontroller as the core control chip and the voltage and current double closed-loop control algorithm to achieve the energy efficient two-way flow of lithium battery and the function of constant voltage, constant current charge and discharge. The experiments prove that the converter can achieve the basic purpose of the charge grid-side power factor to be 1 and the discharge grid-side power factor to be-1 .
