24 パルス システムの高調波キャンセルの効果は、ブリッジ間の位相差の精度に依存します。 Precise calculation of the phase-shift winding turn ratios is essential, as winding deviations and assembly errors during manufacturing can affect the final phase-shift angle. Yulan Transformer records the turn counts for phase-shift windings on a per-unit basis and verifies inter-winding phase angles during factory acceptance testing, maintaining deviations within ± 0.5 ° .
