<p>An 18 pulse circuit is formed with three six pulsed bridge stages [11-13]. Two of these connect with transformer stages [15,17] providing +10 and - 10 degree phase shifts. The other stage is a star/delta circuit [16]. The inputs to the circuits is a three phase supply. The converter provides a DC voltage output having a low higher harmonic content.</p> |
