摘要：BOOST电路在光伏最大功率点跟踪的DC-DC转换拓扑中被广泛应用，系统的动态性能受到电路参数的影响。为设计高性能的最大功率跟踪系统，提高系统的动态响应速度，给出了带耦合电感的交错并联BOOST变流器拓扑。并在此基础上详细分析了其稳态和动态特性，最后以60 W光伏发电蓄电池充电DC-DC变流器的仿真波形验证了设计的合理性。

Abstract: BOOST is widely used as DC-DC converter in the photovoltaic maximum power point tracking control system. The circuit parameter has been proposed to affect the transient quality of system. To designing a maximum power point tracking control system of high quality and improving the transient response of the system, an interleaved BOOST converter with coupled inductors was introduced. Based on this topology, the steady and transient-state analysis were given in detail. The simulation waveforms of the DC-DC converter for a 60 W photovoltaic battery charging system show the rationality of design.
