Abstract
An AC/DC or DC/AC converter includes a single hexagon transformer with each side connected to opposite polarity DC terminals through two pairs of SCR devices gated in sequence synchronously with the frequency of the AC lines, gating in a pair lagging gating of the next SCR device in the adjoining pair, to create a 24-pulse output, while minimizing AC line harmonic contents, especially the 11th and 13th harmonics.
