Editorial: Construction and technology of power semiconductor devices

Power electronic systems play a dominant role in making more efficient use of electric power in many appliances and offer a wide range of ways to control how electrical energy is transported and used. These systems enable automation and robotics, and play a very important role in traction by enabling the use of electric cars and trains. Effective energy delivery and conversion control, including power generation from renewable energy sources and smart energy distribution grids, will continue to grow in importance in future, due to the rising demand for energy.
