Module special for carrier power source of electric energy meter

The invention provides a module special for a carrier power source of an electric energy meter, belongs to carrier power source power supply devices in the electric instrument and meter industry and relates to the technical field of fundamental theory of electrical engineering, power electronics, electronic measurement and the like. The module special for the carrier power source of the electric energy meter solves the problems that an existing carrier power source is large in fluctuation when impacted by a power grid and effective transmission of carrier communication data is affected. The module special for the carrier power source of the electric energy meter is composed of a voltage conversion circuit and a short-circuit protection circuit, can achieve stable voltage output, and can provide large instantaneous current and low ripple waves. In case of short circuits, the power module can achieve a good protective function, prevents devices from being damaged, saves maintenance cost, and guarantees normal operation of communication of the electric energy meter.
