Description

Technical field [0001] The invention relates to a power source, in particular to a high-precision battery-formed power source. Background technique [0002] When the battery is manufactured, it is necessary to activate its internal positive and negative materials through a chemical conversion process to improve the overall performance of the battery, such as charge and discharge, self-discharge, and storage. In the early days, the power source used for chemical conversion was unidirectional DC / DC. The power source could only charge the battery, and the discharge process was completed by resistive load, which resulted in low energy efficiency and poor energy conservation. With the development of technology, a variety of new two-way DC / DC power supplies have emerged. This type of power supply can not only charge the battery, but also feed the energy discharged from the battery back to the grid to realize the reuse of energy. [0003] The topological structure of bidirectional DC / DC ...
