Current power semiconductors are characterized by high switching speeds, higher voltage and current ratings, greater reliability and lower prices than their predecessors. Two decades of quiet evolution in power semiconductors have produced not only improved SCRs, but other thyristors such as triacs, rectifiers and power transistors. The devices in this article are those that dissipate enough power in normal operation that power dissipation is a limiting factor in their application. Very-high-power applications include electric power generation and distribution, railroad and electric-car transportation, uninterruptible power supplies for large computer backup equipment and others where dissipation levels are typically in the range of hundreds to thousands of watts.
