Abstract

The invention relates to a mobile emergency power supply based on a system converter in the technical field of power supplies, which comprises a battery module, the multi-functional converter, a direct current reactor, three alternating current reactors, two direct current voltage-stabilizing capacitors, eight contactors and a main control circuit module. A DSP2812 digital signal processor is used as a core controller, a touch screen is adopted as a system upper computer, the running state of a system is selected, a running command signal of the system is given out, and the operation is simple. The core part of the power supply is the multi-functional converter, and the system can work in one state of direct current conversion, PWM rectification and PWM inversion by leading the contactorsto close different loops. Electrical energy can be derived from four inputs of wind energy, solar energy, commercial power and a diesel engine, thereby effectively improving the reliability of the system.

Description

technical field [0001] The invention relates to a device in the field of electric power supply technology, in particular to a mobile emergency power supply based on a system converter. Background technique [0002] Mobile emergency power supply has been widely used in various industries, such as backup power supply for modern buildings, emergency power supply in emergency rescue and disaster relief, medical treatment, fire fighting, military equipment, etc., and the demand continues to increase. In recent years, with the introduction of the micro-grid concept and the continuous development of distributed power generation systems, mobile emergency power supplies can also be used as backup support for small power grids, and as a grid-connected intermediary for various new energy sources. [0003] The mobile emergency power supply is based on fully controlled power electronic device IGBT and PWM conversion technology. Compared with the traditional mobile emergency power supply ...
