VOLTAGE CONVERTER AND SERVICE BOARD

The present application discloses a voltage converter and a service board. On the basis of a power supply architecture of a power conversion circuit, ultrafast dynamics are achieved by means of an added voltage conversion circuit, and the voltage conversion circuit can be achieved by means of a transformer-based topology, to achieve rapid and low-loss energy transfer, thereby meeting the requirements of system ultrafast dynamics. The voltage conversion circuit comprises a converter, a first capacitor and a second capacitor, and the converter can realize establishment of an energy transfer channel between the first capacitor and the second capacitor. By using the voltage conversion circuit, the number of capacitors required by the service board can be reduced on the premise of meeting the power supply dynamic performance of a service chip, in other words, by using the voltage conversion circuit, the power supply dynamic performance of the service chip can be improved without increasing the number of capacitors
