WebMay 7, 2024 · With less inductance in the primary winding, there is less inductive reactance, and consequently a much larger magnetizing current. A substantial amount of the current through the primary winding merely works to magnetize the core rather than transfer useful energy to the secondary winding and load. WebOct 19, 2015 · Compensating the primary inductance improves the power factor and reduces the required Volt-Ampere rating of the primary power source. The compensation topologies are considered, namely series compensation, parallel compensation, and series-parallel compensation as shown in Figure 4.

WebMutual Inductance. Mutual Inductance is the interaction of one coils magnetic field on another coil as it induces a voltage in the adjacent coil. Mutual inductance is a circuit parameter between two magnetically coupled coils and defines the ratio of a time-varying magnetic flux created by one coil being induced into a neighbouring second coil.
