Abstract

The invention discloses a multi-input boost converter based on Switch-Capacitor networks. The multi-input boost converter is mainly formed by connecting multiple Switch-Capacitor networks in parallel, the capacitor voltages in all the Switch-Capacitor networks are equal, and a larger output voltage is achieved through the mode of accumulating multiple network capacitor voltages. The multi-input boost converter is used for replacing multiple single-input boost converters. The multi-input boost converter allows the input of multiple energy sources, the properties, the amplitude values and the characters of input sources can be identical and can also be very different, the input sources can supply power to loads respectively or simultaneously, and therefore the stability and the flexibility of a system are improved, the preferential utilization of the energy sources is achieved, and system cost is lowered.

Description

technical field

[0001] The invention relates to the field of power electronics, in particular to a multi-input boost converter based on a Switch-Capacitor network. Background technique

[0002] As a non-renewable energy source, fossil energy is being exhausted day by day, and the environmental pollution caused by it is becoming more and more serious. Renewable energy has the characteristics of cheap, reliable, clean and pollution-free, and abundant energy, so renewable energy power generation has shown a good market prospect. At present, the most widely used forms of renewable energy power generation include photovoltaic power generation, wind power generation, fuel cell power generation, hydropower generation, geothermal power generation, etc., but all have shortcomings such as unstable power supply, discontinuity, and changes with climate conditions. Therefore, it is necessary to A distributed power supply system that uses multiple energy sources for joint power supply. ...
