ABSTRACT:
A protection circuit including an energy-storage device, a fusible element, and an overvoltage modulation unit is provided. The energy-storage device stores a first energy and supplies the first energy. The fusible element connected in series with the energy-storage device for constituting a branch circuit. The overvoltage modulation unit is connected in parallel with the branch circuit, wherein when the branch circuit begins to have an overvoltage, an absolute value of a modulating current flowing through the overvoltage modulation unit is increased instantaneously, so that a second energy instantaneously released from the energy-storage device is applied to cut off the fusible element.
