Abstract
A configuration of a thyristor stack is provided. The stack includes thyristors, electrically conductive bars, and reactors that are mounted around the electrically conductive. Heat sinks may be included in the thyristor stack to assist in heat dissipation, although they may not be necessary. A method for constructing a thyristor stack is also provided.
