Advantages
· Sinusoidal waveform: Waveform of the emf can be approximately made to a sine wave and distorting harmonics can be reduced or totally eliminated.
· Economical :Conductor material , copper , is saved in the back and front end connections due to less coil-span.
· Higher efficiency: As the high frequency harmonics are eliminated, the eddy current and hysteresis losses are reduced which increases overall efficiency
