Description

Technical Field

[0001] This utility model relates to the field of magnesium-air battery technology, specifically to a novel magnesium-air emergency power conversion circuit. Background Technology

[0002] Traditional magnesium-air batteries suffer from problems such as a single output voltage and poor adaptability to load fluctuations. Existing patent CN202422417179.2, entitled "An Excitation Power Supply and Power Converter," describes a method where "when the switch is open, its energy storage element can be charged through the conversion circuit to store electrical energy. When the switch is closed, the energy storage element can discharge to the connected excitation fuse through the switch, igniting the ignition tube in the excitation fuse, thus enabling the excitation fuse to perform its fuse function; that is, the discharge of the energy storage element can meet the transient power required for the ignition tube to operate. Moreover, the electrical energy received by the ignition tube comes from the storage of the energy storage element, rather than directly from the output of the conversion circuit; therefore, the output response speed of the excitation power supply is greatly improved, and the rated power of the conversion circuit can be much less than the maximum transient power, thereby significantly reducing the size and no-load loss of the excitation power supply, and also reducing the cost of the excitation power supply." Therefore, while the reference patent optimizes transient response through the energy storage element, it does not address the need for multiple voltage outputs.

[0003] In summary, a novel magnesium-air emergency power conversion circuit was designed. Utility Model Content
