Abstract

The invention discloses a transformer with a high set-up ratio, a solar inverter and a solar battery system. According to the invention, the low output voltages of power sources are converted to high output voltages through the transformer with the high set-up ratio; and according to the specific application and different control methods, the outputs of the transformer with the high set-up ratio from a first technical scheme to a fourth technical scheme can be standard direct current voltages or controlled and modulated specific voltage wave forms. By using the transformer with the high set-up ratio, the solar inverter and the solar battery system, the defects of small set-up ratio, long transmission path, large additional loss, low energy conversion efficiency and the like in the prior art can be overcome, so as to realize the advantages of large set-up ratio, short transmission path, small additional loss and high energy conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of boosting circuit and grid-connected solar power generation, in particular, to a converter with a high boosting ratio, a solar inverter and a solar battery system. Background technique [0002] In recent years, renewable energy power generation systems based on wind energy and solar energy have been used more and more in the world. For solar grid-connected power generation systems, in addition to the current mainstream concentrated high-power solar power plants, distributed solar grid-connected power generation systems, because they can optimize the working status of solar panels, can improve the system's annual life in most cases. Power generation has been paid more and more attention and has become a research hotspot. [0003] Among them, the distributed power generation system based on solar micro-inverters is particularly eye-catching and widely used in the United States. The core of the solar micro-...
