![]() The classification of secondary transformers can be done into three types based on tapings within a secondary coil-like single-phase, center-tapped, and multi-tapped step-down transformer. of turns within the secondary winding (Ns) is low, the induced emf & the output voltage will be low as compared to the voltage in the primary winding. ‘Vp’ is the voltage within the primary windingĪs compared to the primary winding, the number of turns within secondary winding should be low (Np>Ns) to work the transformer as a step-down transformer. ‘Vs’ is the voltage within the secondary winding The formula which is used for designing a step-down transformer is given below. So, the generated EMF strength mainly depends on the no. When the secondary coil comes in contact through this magnetic flux, then an EMF can be induced on it. Once AC is given to the primary winding, then a magnetic flux can be generated throughout the transformer core, the magnetic field completes its lane. The primary coil is connected to the AC power source directly whereas the secondary coil is connected to the load. ![]() ![]() We know that each transformer includes two windings or coils like primary & secondary. ![]()
