中文摘要:
      设计了一种基于变频控制芯片L6565D的宽电压范围双管反激电源,其输入电压范围为200~1 000 V,作为系统的辅助电源应用于光伏电站中;L6565D通过采集输入电压的变化情况实现不同电压段的电流环限流点的调节,同时利用检测变压器磁复位状态来控制两个开关管工作于谷底导通模式,实现软开关功能。其准谐振工作模式降低了开关管开通损耗,改善了电磁兼容EMC(electromagnetic compatibility),提高了整机效率,节约了成本。目前该款电源已经成功应用到光伏系统中,取得了良好的效果。
英文摘要:
      In this paper, a kind of dual-switch flyback power supply with wide voltage range was designed, which was based on a variable-frequency control chip L6565D. Its input voltage range was 200~1 000 V, and it was usually used as an auxiliary power supply for the system in a photovoltaic(PV) power station. By collecting the changes in input voltage, the control chip L6565D can realize the regulation of current-limiting point on the current loop in different voltage segments; meanwhile, the transformer magnetic reset state was tested to control the two switch tubes to work in the bottom of conduction mode, thus achieving the soft-switch function. The quasi-resonant operating mode reduced the turn-on loss of the switch tube, improved the electromagnetic compatibility(EMC) and the efficiency of the machine, and saved the cost. At present, this type of power supply has been successfully applied to PV systems with a satisfying effect.
