Description
Description:
A power transformer is a device that helps to increase the voltage of a power supply. It is used to convert electrical energy into a higher voltage, or convert lower voltage electrical energy into a higher one. The function of the transformer is to change the alternating current (AC) into direct current (DC).The primary winding of a transformer has high-voltage windings that are connected in series with each other, while the secondary winding has low-voltage windings that are connected in parallel with each other. The primary and secondary windings are connected by a core material, which is usually ferrite iron.Power transformers are used in many different applications including power generation, telecommunication networks, industrial machinery and heating systems.
