Abstract

A model is derived to estimate the primary-side inductor current of a discontinuous current mode Flyback converter. The model is validated by comparing the current estimated by the model to the current sensed using a sense resistor. The model was applied in a photovoltaic (PV) system which interfaced a PV module to a battery via a Flyback converter in order to charge a 12V lead acid battery. The system successfully controlled power flow from the PV module according to a model-based current perturb and observe (P&O) maximum power point tracking (MPPT) algorithm.

基于模型的电流MPPT控制的光伏发电系统反激变换器

推导了一种估计断续电流型反激变换器一次侧电感电流的模型。通过将模型估计的电流与检测电阻检测到的电流进行比较，验证了模型的有效性。该模型应用于光伏(PV)系统，该系统通过反激变换器将光伏组件与电池连接，为12V铅酸电池充电。该系统采用基于模型的电流扰动与观测(P&O)最大功率点跟踪(MPPT)算法，成功地控制了光伏组件的潮流。
