Conventional boost converters used for fuel‐cell applications suffer from a slow dynamic response, due to their non‐minimum phase nature. It is the main challengeable problem in the development of boost topologies working in continuous‐conduction mode (CCM). In order to eliminate the mentioned disadvantage, a boost converter is proposed in this article which is capable to give a high voltage gain. From viewpoint of the boosting feature, the proposed topology is more appropriate to connect a low input voltage to a higher dc voltage of load. Moreover, the duty‐cycle‐to‐output‐voltage transfer function of this converter is free from the right‐half‐plane zero (RHPZ) and therefore, its dynamics are simpler and faster compared with the classical boost converter. To cancel the RHPZ, improve the dynamic behavior and enhance the voltage transfer gain, a separate forward path is provided using a transformer and an additional capacitor in the output node for transferring the input energy to the output load during the switch‐on time interval of the power switch. For derivation of the converter model, the steady state analysis is given in details and the required equations are formulated. The transfer function expression is obtained using the averaging model of the converter and then, the description and comparisons are introduced to reveal the features and superiority of the proposed converter. Also, a laboratory set‐up of the suggested dc/dc boost converter working in CCM is built and tested.

新的升压转换器的建模和实现,消除了右半图零

由于其非最小相位特性,用于燃料电池应用的传统升压转换器具有较慢的动态响应。在以连续导通模式(CCM)工作的升压拓扑的发展中,这是主要的挑战性问题。为了消除上述缺点,本文提出了一种能够提供高电压增益的升压转换器。从升压功能的角度来看,建议的拓扑结构更适合将低输入电压连接到较高的负载直流电压。此外,该转换器的占空比到输出电压的传递函数不受右半平面零(RHPZ)的影响,因此,与传统升压转换器相比,其动态特性更简单,更快。为了消除RHPZ,改善动态行为并提高电压传输增益,在输出节点中,使用变压器和附加电容器提供了一条单独的正向路径,用于在电源开关的接通时间间隔内将输入能量传输到输出负载。为了推导转换器模型,详细给出了稳态分析并制定了所需的方程式。使用转换器的平均模型获得传递函数表达式,然后进行描述和比较,以揭示所提出转换器的特性和优越性。此外,还建立并测试了建议的在CCM中工作的dc / dc升压转换器的实验室设置。为了推导转换器模型,详细给出了稳态分析并制定了所需的方程式。使用转换器的平均模型获得传递函数表达式,然后进行描述和比较,以揭示所提出转换器的特性和优越性。此外,还建立并测试了建议的在CCM中工作的dc / dc升压转换器的实验室设置。为了推导转换器模型,详细给出了稳态分析并制定了所需的方程式。使用转换器的平均模型获得传递函数表达式,然后进行描述和比较,以揭示所提出转换器的特性和优越性。此外,还建立并测试了建议的在CCM中工作的dc / dc升压转换器的实验室设置。
