Abstract

The present invention relates to the technical field of power supplies, and discloses a control method for a wide-input bidirectional power supply device, which is used for controlling the wide-input bidirectional power supply device. The multi-phase multiple chopping module and the second bidirectional polyphase multiple chopping module enable the energy storage battery pack to output the first DC voltage to the bidirectional DC / AC module, and control the bidirectional DC / AC module to convert the first DC voltage into a first AC voltage ; When the device stores energy, control the bidirectional DC / AC module to convert the second AC voltage provided by the load or the grid into a second DC voltage, and control the first bidirectional multi-phase multi-chopper module and the second bi-directional multi-phase multi-chopper module The module outputs the second direct current voltage to the energy storage battery pack. The invention can adapt to and adjust power sources with different input specifications and bidirectional flow of energy.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a control method for a wide-input bidirectional power supply device. Background technique [0002] With the continuous development of the global economy and the continuous growth of the world population, human beings are increasingly inseparable from electric energy. But now with the rapid development of science and technology, the full utilization of solar photovoltaic power generation, wind power generation, renewable energy, power grid or other power supply combined with the full utilization of various energy storage battery packs, etc., make human beings face many power supply problems. Problems: (1) The demand for electric energy continues to grow, and with the continuous consumption of traditional fossil energy coal, oil, and natural gas, and they are non-renewable, it is impossible for them to meet all our power supply needs; (2) As With the popularization of solar...
