摘要
设计了一种基于低成本数字处理器TMS320F28020和专用PWM集成芯片TL494的便携式离网型光伏逆变电源,主电路采用比较简单的隔离型两级变换拓扑,控制回路采用双单片机的控制方案,并给出了样机的实验结果。
A portable off-grid inverter power supply based on low-cost digital single processor TMS320F28020 and specialized PWM integrated chip TL494 is designed. The main circuit utilizes a relatively simple topology with two-stage conversion. Besides, the control scheme takes advantage of a control program with dual MCU. Good experimental results are given.
