Zusammenfassung:The invention provides a power converter, a control method and communication equipment. The power converter comprises a first power conversion circuit, a transformer, a second power conversion circuit and an energy absorption circuit. The input end of the first power conversion circuit is connected with a power supply, and the output end of the first power conversion circuit is connected with a primary winding of the transformer. The input end of the second power conversion circuit is connected with the secondary winding of the transformer, and the output end of the second power conversion circuit is connected with the load. The energy absorption circuit is connected in parallel with two ends of the switching device of the second power conversion circuit. And the energy absorption circuit is used for absorbing peak voltage at the two ends of the switching device of the second power conversion circuit. Wherein the duty ratio of the driving signal of the switching tube of the first power conversion circuit in t
