Many of the photovoltaic (PV) panels generate the low amounts of the voltages under the limited values of the powers. In order to increase these voltages to be applicable for grid utilization, DC‐DC boost converters are used. A novel nonisolated transformer‐less switched‐capacitor‐based DC‐DC power boost structure is combined with the quadratic converter in this study. The proposed converter has many advantages such the low‐voltage stresses on the power components, higher voltage‐gain, and ability to supplying the load under the low amounts of the switching time intervals. These features lead to fewer amounts of the currents for the power components in the topology for the continuous conduction mode which means less dynamic losses and higher efficiency. Another advantage of the proposed converter is including only one power switch that simplifies the controller design for implementation purposes. A comprehensive mathematical analysis is presented and simulation with MATLAB/SIMULINK and implemented hardware test results confirm the theoretical investigations.

无变压器单开关升压转换器，具有高电压增益和缓解的电压应力，适用于光伏应用

许多光伏（PV）面板会在有限的功率值下产生少量的电压。为了增加这些电压以适用于电网利​​用，使用了DC-DC升压转换器。在这项研究中，一种新颖的基于非隔离式无开关电容器的DC-DC功率升压结构与二次变换器相结合。拟议的转换器具有许多优点，例如功率组件上的低压应力，更高的电压增益以及在少量开关时间间隔内为负载供电的能力。这些功能导致连续导通模式下拓扑中功率组件的电流量减少，这意味着动态损耗更少，效率更高。所提出的转换器的另一优点是仅包括一个电源开关，该电源开关简化了用于实现目的的控制器设计。进行了全面的数学分析，并使用MATLAB / SIMULINK进行的仿真以及已实现的硬件测试结果证实了理论研究。
