Abstract

This paper introduces a digitally controlled multiphase multistage hybrid boost converter (MMHBC) for high voltage capacitor charging applications. Rapid capacitor charging control approach is presented, and topological variations to improve efficiency are examined. The controller provides tight output current regulation, while maintaining real-time current balancing capabilities for superior thermal distribution and converter efficiency. The MMHBC is capable of rapid capacitor bank charging to high voltage by forcing maximum output current at the first stage, which translates into maximal output power during the whole charging period. The controller includes a system governor unit which facilitates additional control aspects for multiphase operation such as phase shedding, soft-start mechanism, and system protection. SMPS operation, rapid capacitor charging, and topological improvements are validated experimentally on a four-phase 12V-to-300V multiphase prototype with a maximum output power of 250W and power density of 2.5kW/Liter.

交错式多级混合式升压电容充电器的数字控制与相位调节以提高效率和功率密度

介绍了一种用于高压电容器充电的数字控制多相多级混合升压变换器(MMHBC)。提出了电容快速充电控制方法，并研究了提高充电效率的拓扑变化。控制器提供严格的输出电流调节，同时保持实时电流平衡能力，以实现卓越的热分布和转换器效率。MMHBC能够通过在第一阶段强制最大输出电流将电容器组快速充电到高电压，并在整个充电期间转化为最大输出功率。该控制器包括一个系统调节单元，便于多相操作的额外控制方面，例如相位脱落，软启动机制和系统保护。在一个最大输出功率为250W、功率密度为2.5kW/ l的四相12v - 300v多相样机上，实验验证了SMPS运行、电容器快速充电和拓扑改进。

期刊介绍： COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
