Abstract

In this paper a high step-up DC-DC converter is proposed with reconfiguration capability that can operate safely without redundancy even if one of its power electronic switches fails. The proposed converter topology provides continuous input current, reduce voltage stress, uniform current sharing among power electronic switches, common grounding features, and also reduces the power handled by the power electronic devices using alternate paths, thereby improves the converter overall efficiency. Further, the control technique used for the converter reduces the transients during the healthy and fault operations. A fuse-MOSFET pair has been used to protect the converter from short-circuit faults. The proposed converter characteristic is analyzed in the continuous current mode (CCM), and its features are discussed in detail for both healthy and fault operation. The proposed converter was designed, fabricated and experimentally tested in a closed loop at 100 W to verify the operation and feasibility of the controller designed for both healthy and fault operation.

具有重构功能的高升压直流-直流转换器

本文提出了一种具有重新配置能力的高升压直流-直流转换器，即使其中一个电力电子开关发生故障，它也能在没有冗余的情况下安全运行。所提出的转换器拓扑结构可提供连续的输入电流、降低电压应力、在电力电子开关之间实现均匀的电流共享、共同接地功能，还可减少电力电子设备使用备用路径处理的功率，从而提高转换器的整体效率。此外，转换器采用的控制技术还能减少健康和故障运行期间的瞬态。保险丝-MOSFET 对用于保护转换器免受短路故障的影响。在连续电流模式（CCM）下分析了拟议的转换器特性，并详细讨论了其在健康和故障运行时的特点。对所提出的转换器进行了设计、制造，并在 100 W 的闭环中进行了实验测试，以验证所设计的控制器在健康和故障运行时的操作性和可行性。
