基于 交错反激拓扑 的 微型逆变器 根据其 原边 电感电流 可以将 反激变压器 分为电感电流 连续模式、临界模式、断续模式 这 三个工作模式。本文 通过 详细分析 微型逆变器 的 工作原理,研究 每种 工作模式 相对应的 控制策略,并且 全面计算了 微型逆变器 所使用的 原器件 电压电流应力、分析了 反激变压器的 功率损耗,对比了 每种工作模式的 优缺点,最后 在MATLAB软件中 建立了 300w的 仿真模型,对 每种工作模式下的 控制策略 进行 仿真验证,对 微型逆变器的 设计 和 工作模式的选择 有非常好的 参考价值。
According to the features of primary inductive current, flyback transformer can be set into 3 working modes including continuous mode, boundary mode, and discontinuous mode of inductive current based on interleaved flyback topology-based micro-inverter. In this paper, we made in depth analysis on the working principle of micro-inverter, researched control strategy that is corresponded to each working mode, and comprehensively calculated voltage current stress of each component of micro-inverter. Moreover, by analyzing power consumption of flyback transformer and comparing the advantages and disadvantages of each working mode, a 300w stimulative model was finally established using MATLAB software. Based on this model, we conducted simulation verification of control strategy under each working mode, which is of great reference value to the design and working mode selection of micro-inverter. |
