Background

A power transformer is a stationary electric device that is used to change an ac voltage of a certain value into another voltage or voltages of different values of the same frequency. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and alternating magnetic flux induces alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The secondary induced electromotive force is related to the number of turns of a secondary winding, namely, the voltage is proportional to the number of turns. The main function is to transmit electrical energy, and thus the rated capacity is its main parameter. The power transformer which saves energy is an amorphous alloy iron core distribution transformer, and has the greatest advantage of extremely low no-load loss value. Whether the no-load loss value can be ensured is a core problem to be considered in the whole design process.
