Industrial Control Transformer Electronic Transformer for Elevator

A control transformer (scr for short) is a device that converts DC voltage into AC voltage. It consists of three parts: rectifier circuit, control circuit and inverter. The basic principle is: when the input power is converted into DC through the rectifier, the output voltage is changed in a certain proportion by controlling the switch, so as to achieve the purpose of changing the output voltage.
There is no difference between the principle of control transformer and ordinary transformer, but the use is different. Control transformers are widely used, and can be used for step-up and step-down. The working principle of the control transformer is based on the principle of electromagnetic induction. The transformer has two sets of coils, the primary coil and the secondary coil. When the primary coil is connected to alternating current, the transformer core generates an alternating magnetic field, and the secondary coil generates an induced electromotive force.
