2014 in coal boiler phase-out rectification

FAQ: What is a pulse rectifier and what kinds are there?

Dec 28 2016 · A 12-pulse rectifier uses two 6-pulse rectifiers in parallel (12 diodes) to feed a common DC bus. A transformer with one primary and two secondary windings creates a 30 degree phase shift between the two current waveforms which eliminates the 5 th and 7 th harmonics and reduces current THD to between 10 and 15 percent. Disadvantages of a 12-pulse rectifier are costdue to the special ...

Rectification of a Three Phase Supply using Diodes

We have seen in this tutorial that three-phase rectification is the process of converting a 3-phase AC supply into a pulsating DC voltage as rectification converts the input power supply of a sinusoidal voltage and frequency into a fixed voltage DC power. Thus power rectification changes an alternating supply into a unidirectional supply.
