This work proposes a novel topology of two-output high voltage rate DC-DC converter based on coupled inductor and voltage multiplier cells (VMCs) techniques for renewable energy usages like photovoltaic (PV) systems. The proposed structure has two independent output ports with two voltage gains (M₁ and M₂). Low voltage stress across the power switch and diodes, common ground between input and output ports, high efficiency, and reduced number of elements are the advantages of the suggested converter. The used diodes are switched at zero current switching (ZCS) and zero voltage switching (ZVS) conditions, which reduce the losses of diodes and subsequently increase the power efficiency. Due to the usage of the coupled inductor, there is no need to a high value of the power switch's duty cycle. Therefore, a low conduction loss and higher efficiency can be obtained. On the other hand, because of the reduced voltage stresses, low rated semiconductors can be used for operation of the presented converter, which decrease the cost and the volume. To demonstrate the performance and effectiveness of the proposed topology, operation principles, steady-state and efficiency analysis, and also the comparison assessment are provided. Finally, a 200 W experimental development with 50 kHz operation frequency, 20 V input voltage, and 200 and 100 V loads voltages has been implemented in the lab to prove the mathematical surveys.

一种降低半导体应力的双输出单输入非隔离 DC-DC 转换器

这项工作提出了一种基于耦合电感器和电压倍增器电池 (VMC) 技术的双输出高电压率 DC-DC 转换器的新颖拓扑结构，适用于光伏 (PV) 系统等可再生能源用途。所提出的结构有两个独立的输出端口，具有两个电压增益（M ₁和M ₂). 电源开关和二极管的低电压应力、输入和输出端口之间的公共接地、高效率和减少的元件数量是建议的转换器的优点。所使用的二极管在零电流开关 (ZCS) 和零电压开关 (ZVS) 条件下进行开关，这样可以减少二极管的损耗，从而提高电源效率。由于使用了耦合电感器，因此不需要很高的电源开关占空比值。因此，可以获得低传导损耗和更高的效率。另一方面，由于降低了电压应力，低额定值的半导体可用于所提出转换器的操作，从而降低成本和体积。展示所提出的拓扑、操作原理的性能和有效性，稳态和效率分析，也提供了比较评估。最后，在实验室中实施了具有 50 kHz 工作频率、20 V 输入电压以及 200 和 100 V 负载电压的 200 W 实验开发，以证明数学调查。
