摘要

提出了一种在无线数字通信技术情况下研究并联DC-DC变换器的方法.该方法消除了并联变换器系统中传输控制信号的物理连线,能够屏蔽多种物理连线引入的问题;同时针对DC-DC并联系统的特点,通过对常用的无线收发模块的分析,提出DSP+FPGA 框架方案,使系统的开关频率达到200 kHz,延迟时间缩短到12 μs,并且最终建立了实验平台.通过实验验证了所提并联系统无线控制的有效性.%A method with wireless digital communication technology is proposed to study the parallel DC-DC converter. This method eliminates the physical connections that transmit control signals in the parallel converter system, and it can avoid a variety of problems resulting from the physical connections. At the same time, according to the characteristics of DC-DC parallel system, a DSP+FPGA framework scheme is proposed through the analysis of the commonly used wireless 3 module, with which the system switching frequency can reach up to 200 kHz and the delay time can be shortened to 12 μs.An experimental platform was established,and experimental results verified the validity of the parallel system with wireless control.
