摘要

DC-DC变换器输入串联输出并联的组合技术广泛应用于大功率高电压场合。为了实现模块扩展连接后的平均运行，研究模块电源串并联组合后的输入均压和输出均流特性，提出一种从输出端进行模块均流的控制策略。控制策略包含2个环路，分别为输出电压环和输出均流环。所有模块公共的输出电压环采样组合系统的输出电压进行反馈调节，每个模块具有的输出均流环采样模块的输出电流进行平均控制。所提控制策略中所有的采样和控制芯片均在低压输出侧，可省去隔离单元，提高系统可靠性。选取半桥LLC谐振拓扑作为子模块搭建原理样机，验证所提输出均流控制方法的有效性。

The input-series output-parallel combination technology for DC-DC converters is widely applied in high-power and high-voltage fields. To realize an average operation after the expansion and connection of modules, the characteristics of input voltage-sharing and output current-sharing after the series-parallel combination of module power supplies are studied, and a control strategy for module current-sharing on the output side is proposed, which consists of an output voltage loop and an output current-sharing loop. The common output voltage loop of all the modules samples the output voltage from the combined system for feedback regulation, while the output current-sharing loop of each module samples the output current from the module for average control. All the sampling and control chips under the proposed control strategy are on the low-voltage output side, which can eliminate an isolation unit and improve the system reliability. A half-bridge LLC resonant topology was selected as a sub-module to build a prototype, and results verified the effectiveness of the proposed output current-sharing control method.
