Embodiment Construction
[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood, however, that the invention may be embodied in various forms, and some exemplary and non-limiting embodiments are shown in the drawings and described below, and are not intended to limit the invention to the specific embodiments described. .
[0035] figure 1 Shown is the main circuit topology of the non-electrolytic capacitor cascaded H-bridge STATCOM system of the present invention, including: three-phase power grid, three-phase reactive load, filter inductor and three-phase cascaded N double-Buck multiplexed H-bridges, N≥ 2. The dual-Buck multiplexed H-bridge includes: four full-control switch tubes S1-S4, two decoupling inductors L r1 and L r2 , three film capacitors C r1 、C r2 and C d ; the C r1 through L r1 Connected to the midpoint of the first bridge arm of the H bridge to form the first bidirectional Buck...
