COT PARALLEL CIRCUIT AND POWER SUPPLY DEVICE

This application provides a COT parallel circuit and a power supply device. After receiving a first power signal output by a first phase converter, the COT multiphase parallel circuit may output a first pulse signal to a second phase converter, where the first pulse signal is used to indicate the second phase converter to output a second power signal. Further, the COT multiphase parallel circuit may output a plurality of power signals in one period of a RAMP signal. A high-frequency power signal can be output without increasing a frequency of the RAMP signal, thereby reducing difficulty of implementing a high-frequency COT multiphase parallel connection.
