摘要

由于光伏阵列的非线性特性，从太阳能电池阵列中提取最大功率/能量是一个值得关注的问题，在面板上连接到DC-DC转换器。阵列i-v特性中的最大功率点随太阳辐照度和温度的变化而变化。太阳能电池阵列模拟器(SASs)用于模拟不同环境条件下光伏(PV)电池板的输出，以评估电力调节系统(PCS)的动态性能。提出了一种半桥LLC谐振DC-DC变换器。该变换器的主开关电压为零，从而减少了损耗。它还减少了谐振电容上的电压应力。变频器的输出可以通过调频控制来控制。

Half bridge LLC resonant DC-DC converter for solar array simulator application

Extraction of maximum power/energy from solar array is a matter of concern, in the panel connected to DC-DC converters, because of the nonlinear characteristics of the PV array. Maximum power point in the i-v characteristics of the array varies with the solar irradiance and temperature. Solar array simulators (SASs) are used to emulate the photovoltaic(PV) panel output under different environmental conditions and to evaluate the dynamic performance of Power Conditioning System(PCS). This paper proposes a half bridge LLC resonant DC-DC converter. This converter has zero voltage turn on of its primary switches thus reducing losses. It also reduces the voltage stress across the resonant capacitor. The output of the converter can be controlled by frequency modulation control.
