Embodiment Construction
[0025] The solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] figure 1 Shown is the topology diagram of the cascaded SVG system based on double BUCK sub-modules.
[0027] The cascaded SVG system based on double BUCK modules includes a three-phase chained SVG circuit and three inductors L, and one end of the three-phase link of the three-phase chained SVG circuit is respectively connected to the AC power grid through an inductor L A, B, C three-phase, the other end of the three-phase link adopts star connection. The inductance L is used to suppress the output harmonics of the device and provide reactive power to the grid.
[0028] Each phase link of the three-phase link includes at least one double BUCK sub-module connected in series, refer to figure 2 , the double BUCK submodule includes:
[0029] The reverse series switch tube T 1 and diode D 1 , reverse series switching tu...
