Problems solved by technology
[0002]With the rapid development of industry, life and production have increasingly strict requirements on power electronic circuits, and the industry also needs higher gain boost circuits, while the traditional Boost circuit has been unable to meet the needs of industry
The traditional method of cascading boost voltage through multiple Boost link circuits is not only costly, but also reduces the stability of the system due to the increase in the number of switch tubes. If one of the links fails, the entire system will collapse.

The invention discloses a Z network boosting circuit system, which comprises a first Z network for first-stage boosting, a second Z network for second-stage boosting, a switching circuit, a fly-wheel diode and a load, wherein the first Z network and the second Z network have different structures; the switching circuit comprises a switching diode, a first energy storage capacitor, an auxiliary capacitor and a switching transistor. Through adopting two stages of Z networks for boosting and only arranging one switching transistor, the needed boosting gains can be ensured, and the stability of the boosting circuit is also enhanced.
Description
technical field [0001] The invention relates to the technical field of boosting circuits, in particular to a Z-network boosting circuit system. Background technique [0002] With the rapid development of industry, life and production have increasingly stringent requirements for power electronic circuits, and the industry also needs a higher gain boost circuit, but the traditional Boost circuit can no longer meet the needs of the industry. The traditional method of cascading boost voltage through multiple Boost link circuits is not only costly, but also reduces the stability of the system due to the increase in the number of switch tubes. If one link fails, the entire system will collapse. [0003] Therefore, how to provide a highly stable Z-network boosting circuit system is a problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a Z-network boosting circuit system, which uses a two-stage Z-...
