The role of the power transformer

The main function of the power transformer is to make the primary side completely insulated from the secondary side, and also to isolate the circuit. In addition, the high frequency loss of the iron core is used to restrain the high-frequency clutter into the control loop. The use of power frequency transformer to make the secondary suspension to the ground can only be used in the case of small power supply range and short line. At this point, the system's capacitive current to the ground is too small to cause personal injury. Another very important role is to protect personal safety and isolate dangerous voltages.

Power transformer is a soft magnetic component, its function is power transmission, voltage conversion and insulation isolation, in the power technology and power electronics technology has been widely used.

Power transformers can also play a role in protecting equipment, saving energy and regulating voltage. It is used in almost all electronic products, and its principle is simple, but the winding process of the transformer will have different requirements according to different use occasions (different uses).

The main functions of the transformer are: voltage conversion; Impedance transformation; Isolate; Voltage regulation (magnetic saturation transformer), etc., the commonly used core shape of the transformer is generally E and C core.
