Preface
The adverse impact on the environment resulting from carbon emissions into the atmosphere is widely accepted worldwide. The carbon emission can be reduced by taking two approaches. The first approach is based upon energy conservation. Energy conservation can be achieved without compromising the standard of life in our society by improving the efficiency for the management and distribution of power. Power semiconductor devices are recognized as a key component for achieving this goal [1]. It is estimated that at least 50% of the electricity used in the world is controlled by power devices. With the wide spread use of electronics in the consumer, industrial, lighting, and transportation sectors, power devices have a major impact on the economy because they determine the cost and efficiency of systems. The second approach to mitigating carbon emissions is by the development of renewable energy sources such as wind power and solar power. These installations require power electronic inverters to convert the generated power to a well-regulated 60 Hz AC power that can be distributed to consumers and the industry. Due to the relatively high power levels involved, the power semiconductor devices used in these applications must have high voltage and current handling capability. In the 1950s, the power rectifiers and thyristors were introduced to replace the existing vacuum tubes. The solid state devices offered much smaller size, improved ruggedness, and greater efficiency. Over the last six decades, the power ratings of thyristors have steadily grown. The current handling capability has
