a new circuit topology of a phase-locked loop that can be used for synchronising a singlephase wind turbine generator (WTG) with the low voltage utility grid. The circuit is based on the time-delay digital tanlock loop (TDTL) architecture and

对软启动器搭建的基本拓扑，用于初学者的研究，是在matlab环境下搭建的，用于仿真计算。(The basic topology of the soft starter, which is used for beginners, is built in the MATLAB environment for simulation.)
