1results about How to "Improve charge stability" patented technology

The application provides a fast charging circuit of an energy storage device and a charging method and a charger thereof, wherein the charging circuit comprises a forward conversion module, the forward conversion module outputs a first stable current or a second stable current to the energy storage device through a transformer; an energy storage capacitor is electrically connected to an output power supply of the forward conversion module, and the energy storage capacitor is electrically connected to the energy storage device through a control switch; when the output of the charging circuit is switched from the first stable current to the second stable current, the control switch is closed, the energy storage capacitor charges the energy storage device, so as to accelerate the switching process from the first stable current to the second stable current; the energy storage capacitor is electrically connected to an output port of the transformer, the output port of the transformer is allowed to be switched, so as to maintain the voltage of the energy storage capacitor at a preset voltage. The application can generate continuous current and high-quality pulse current, and the charging efficiency is high.
