Abstract
A three-phase AC power controller has three strands, each having an input and an output. Five pairs of valves are connected antiparallel for rotating field reversal. The first input is connected to the first output by way of a first pair, the second input is connected to the second output by way of a second pair and to the third output by way of a third pair, and the third input is connected to the second output by way of a fourth pair and to the third output by way of a fifth pair. An RC half-branch is connected as a snubber circuit to each input and to each output. These RC half-branches are each interconnected via a transverse connection.
