Three Phase Twelve Pulse Equation


-->

Three Phase Twelve Pulse Equation. The 30 degrees phase shift was introduce to eliminate the fifth and seventh harmonics. Basically a rectifier eliminates the negative cycle of ac, so by principle we can get a much better result if we do rectification another time.

Why 3Phase Power? Why Not 6, 12 or More for Transmission?

The 30 degrees phase shift was introduce to eliminate the fifth and seventh harmonics. An increasing number of pulses reduce the harmonic contents in a line current. Basically a rectifier eliminates the negative cycle of ac, so by principle we can get a much better result if we do rectification another time.

However, this technique is profound, has high cost, complex construction, and needs to be large in size.
