Twenty-Four Pulse Rectifier

Twenty-four pulse rectifier: installed in the subway, light rail traction substation, for train operation to provide traction power. In the substation through the rectifier transformer, rectifier to the DC contact network power supply.

A single rectifier consists of two three-phase six-pulse full-wave rectifier bridges, one of which is connected to the Y-type winding on the secondary side of the rectifier transformer, the other is connected to the Δ type winding on the secondary side of the rectifier transformer, and the two rectifier bridges are connected in parallel to form a twelve-pulse rectifier.

Two rectifier bridges are connected in parallel to form a twelve-pulse rectifier.

Two rectifier units in each traction substation are operated in parallel to form an equivalent twenty-four-pulse rectifier.
