More Information
Summary:The utility model discloses a high switching rate emergency power supply comprising a battery pack, a high speed soft switch serially connected between a power grid and a load, a bidirectional converter serially connected between an output end of the high speed soft switch and the battery pack, and a controller used to control the switching on/off of the high speed soft switch. The controller is respectively connected with an input end and an output end of the high speed soft switch and the battery pack, and can be used to acquire the voltages of the input end and the output end of the high speed soft switch and the battery pack. The controller is connected with a control end of the bidirectional converter, and can be used to control the starting and the stopping of the bidirectional converter. Compared to the prior art, the switching time of the emergency power supply from the power grid power supply to the emergency power supply under the abnormal condition of the power grid can be obviously reduced, theref
