Abstract: A resonant converter, a control method of a resonant converter, and a related device. The resonant converter includes a control circuit, a drive circuit, and a switch circuit. The control circuit is configured to generate, based on a target output electrical parameter of the resonant converter, a first pulse signal and a second pulse signal that have different frequencies. The control circuit is further configured to: obtain a first drive signal based on the first pulse signal and the second pulse signal and send the first drive signal to the drive circuit. The drive circuit is configured to: convert the first drive signal into one or more second drive signals and send the one or more second drive signals to the switch circuit, to turn on or off a switch component in the switch circuit.

Abstract: An electric power conversion system and a vehicle, to improve vehicle availability. The electric power conversion system may receive electric energy provided by a first power supply, and supply power to at least one load module. The system may include a first direct current to direct current conversion module and a second direct current to direct current conversion module. The first direct current to direct current conversion module is configured to perform voltage conversion processing on the electric energy and provide the electric energy to the at least one load module. The second direct current to direct current conversion module is configured to perform voltage conversion processing on the electric energy and provide the electric energy to the at least one load module.
