摘要

针对单级电流型逆变器共模电流问题和储能电感磁饱和问题,采用带旁路开关和多绕组高频变压器的多输入电流型逆变器电路拓扑。针对多能源系统能量管理和环路解耦问题,提出基于功率占比的主从功率能量管理单周期控制策略,旨在实现不同供电模式的稳定运行、不同供电模式的平滑切换和控制环路的解耦运行。对系统的电路结构、能量管理控制策略、小信号模型等进行深入的理论分析,设计了系统的控制环路,最后研制了2.5 kVA光伏-风力双输入单级电流型逆变器样机,对所采用的电路拓扑和能量管理控制策略进行验证。

Abstract

Concerning the common-mode current problem and the magnetic saturation problem of energy storage inductor in the single-stage current-source inverter, a multi-input current-source inverter with bypass switches and multi-winding high-frequency transformers is adopted. Concerning the energy management and the loop decoupling problem of the multi-energy system, a one-cycle control and master- slave power energy management strategy based on power ratio is proposed, which aims to realize the stable operation of different power supply modes, smooth transformation of different power supply modes, and decoupling operation of the control-loop. The intensive theoretical analysis of the circuit structure, energy management control strategy, and small-signal model of the system is carried out, the control loop of the system is designed, and finally a 2.5 kVA prototype of single-stage current-source inverter with photovoltaic-wind dual-input is developed to validate the adopted circuit topology and energy management control strategy.
