本文的目的是研制一种具有双输入电源的高升压隔离变换器。所提出的转换器具有两个输入端口，用于同时将两个不同的低电压输入电源转换为具有高电压的稳定输出功率。此外，该变换器还可以满足依赖于充电和放电储能机制的电源管理的双向潮流需求。根据各种情况，本文提出的变换器的运行状态可分为独立运行状态、联合供电状态和充放电状态三种状态。实验结果验证了所设计电路拓扑的有效性，通过所提出的变换器工作可以实现高效率转换、高升压比和双向潮流的目标。
The objective of this paper is to develop a high step-up isolated converter with two input power sources. The proposed converter has two input ports for simultaneously converting two different input power sources with low voltages to a stable output power with a high voltage. Moreover, the demand of bidirectional power flow, which is dependent on the power management for charging and discharging power storage mechanisms, can also be satisfied in the proposed converter. According to various situations, the operational states of the proposed converter can be divided into three states, including a stand-alone state, a united power supply state, and a charge and discharge state. The effectiveness of the designed circuit topology is verified by experimental results, and the goals of high-efficiency conversion, high step-up ratio, and bidirectional power flow can be achieved by the proposed converter operation.
