Abstract

The invention provides a resonance type multi-input direct-current transformer for new energy power supply. The direct-current transformer is composed of a full-bridge inverter circuit, a resonance unit, a rectifier unit, and a plurality of input units. The multiple input units are connected in parallel; two common terminals of the multiple input units connected in parallel are respectively connected with two input terminals of the full-bridge inverter circuit; two output terminals of the full-bridge inverter circuit are connected with the input terminal of the rectifier unit; the output terminal of the rectifier unit is connected with a medium-voltage direct-current bus; and two ends of the resonance unit are respectively connected with two output terminals of the full-bridge inverter circuit. The provided resonance type multi-input direct-current transformer has advantages of high power density and stable output voltage.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a resonant multi-input DC transformer suitable for new energy supply. Background technique [0002] Due to the increasing shortage of resources such as oil, coal and natural gas, serious environmental pollution, and global warming, the development and utilization of renewable energy has attracted more and more attention. Renewable energy power generation mainly includes photovoltaic, wind power, fuel cell, hydropower, geothermal and other types, all of which have defects such as unstable power supply, discontinuity, and changes with climate conditions, and require the use of a power supply system that combines multiple new energy sources. [0003] The traditional multi-renewable energy distributed power supply system is to convert solar cells, wind generators, fuel cells and other renewable energy power generation equipment through an independent unidirectional DC converter...
