摘　　要： 本文介绍的双向DC-DC变换电路采用非隔离Buck-Boost电路作为主电路,运用同步整流技术,以STM32F103ZET6单片机为控制核心,利用软件补偿网络、数字校准技术以及PID控制算法使得系统控制精度高。电池充放电模式效率高且可自动切换。整个系统结构简明,人机界面友好,运行稳定可靠。 A bi-directional DC-DC conversion circuit is designed by using a non-isolated Buck-Boost circuit as a main circuit, using synchronous rectification technology with STM32F103ZET6 microcontroller core in this paper. The use of software compensation networks, digital calibration technology and PID control algorithm enables the sys- tem control and grants high accuracy. Battery charge and discharge mode has high efficiency and can automatically switch. The entire system structure is simple, the man-meachine interface is friendly, operation is stable and relia- ble.
