摘　　要：文章在分析并网逆变器拓扑和控制策略基础上研制了一台600W单相并网逆变器,采用前级Boost升压后级工频变压器隔离的拓扑结构,控制策略为独立工作模式下的电压有效值控制和并网模式下的瞬时电流控制。该并网逆变器以TMS320F28035为控制核心,分别从硬件电路和控制策略进行分析,同时给出了分时分任务的模块化软件结构设计。实验表明,硬件电路设计合理,软件设计逻辑正确,能够确保逆变器在并网状态下平稳高效精确的运行。Based on the analysis of grid inverter topology and control strategy develop a 600 w single-phase grid inverter. The inverter uses the Boost and frequency isolation level topology. The control strategy is effective voltage mode for stand-alone and instant current mode for interconnected operation. The TMS320F28035 is chosen as the control core. Introduced the power circuit, drive and detection module design and the time-sharing and tasksharing control software design methods, the experimental results show that the hardware circuit design is reasonable, to ensure the inverter in the efficient and accurate operation smoothly grid-connection condition.
