摘　　要：针对传统两级多个单输入直流变换器型分布式发电系统结构复杂、整体效率低等问题,提出了隔离升压多输入直流变换器型分布式发电系统。该系统由前级Boost型多输入直流变换器和后级Buck型逆变器组成,并采用最大功率输出能量管理控制策略。文中分析研究了这种分布式发电系统的电路拓扑和控制策略,并对其进行建模和实验研究,1 kW隔离升压多输入直流变换器型分布式发电系统的实验证明了所提出设计方案的合理性。Aiming at the complex structure and low overall efficiency of traditional two-stage multi-input DC-DC converter distributed generation system,an isolated boost multi-input DC-DC converter distributed generation system is proposed.The system is composed of the former Boost multi-input DC converter and the latter Buck inverter,and adopts the maximum power output energy management control strategy.The circuit topology and control strategy of this distributed generation system are analyzed and studied,and its modeling and experimental research are carried out.The 1 kW isolated boost multi-input DC-DC converter distributed generation system verifies the rationality of the proposed design.
