Abstract

The invention discloses an electronic heater and a control method thereof, which relate to the power electronic field and are used for reducing the maintenance cost of electronic heater spare parts. The electronic heater includes an auxiliary power supply unit, a control unit, a power regulation unit and a heating source, wherein the auxiliary power supply unit is used to supply power for the control unit; the control unit is used to output detection voltage signals according to an input voltage of the heating source and output power value control signals according to a preset reference power value, and send the detection voltage signals and the power value control signals to the power regulation unit; the power regulation unit is used to obtain output power regulation signals according to the detection signals and the power control signals, and regulate input current of the heating source according to the power regulation signals. The method in the invention is mainly used for various outdoor communication base stations.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an electronic heater and a control method thereof. Background technique [0002] With the development of communication technology, there are more and more outdoor communication base stations. Due to the harsh outdoor environment, in order to ensure the normal operation of the base station, the staff need to install electronic heaters inside the power cabinets, battery cabinets and other cabinets that match the outdoor communication base station. Generally, when the electronic heater inside the above-mentioned cabinet is working, the power supply system supplies power to the heating source to make the heating source generate heat; the auxiliary power supply converts the high voltage provided by the power supply system into a low voltage, and provides the low voltage to the fan; the fan Blow the heat generated by the heating source to the inside of the cabinet to maintai...
