Abstract

In this project, a 18 pulse rectifier has been designed for high voltage application. Three 3 -phase are
obtained from a single three phase source using zig-zag inter connection of conventional single phase transformer. Thus
from the three 3-phase system displaced by 20˚, (obtained using zig - zag connection) 3 six pulse rectifier are obtained
that are cascaded to realize a eighteen pulse rectifier. Phase shift of 0˚ and 20˚ are made using star and zig -zag
connection and thus finally the addition of relevant line voltage. We can also bring down THD of it up to 5.47%
