[0002] The step-down device is a power conversion device that reduces voltage by electromagnetic induction. Its working principle is as follows: the step-down device is mainly composed of an iron core, a primary coil, a secondary coil and a shell. The primary coil is connected to a high-voltage power supply, and the secondary coil outputs a low voltage. When the high voltage passes through the primary coil, an alternating magnetic field is generated. This magnetic field passes through the iron core and the secondary coil. According to Faraday's law of electromagnetic induction, when the magnetic field changes, an induced electromotive force will be generated in the secondary coil. By selecting a suitable turns ratio, the voltage can be reduced. The step-down device can select different output voltages as needed to meet the needs of different equipment. At the same time, the step-down device can also have functions such as overload protection and short-circuit protection to ensure the safe operation of the equipment.
