“…These devices are a dramatic extension of the trend towards mixed technologies in the IC industry, and for the first time, allow the cost efficiencies of integrated circuitry to be applied in the power electronics field. The initial application areas have been in telecommunications (Shackle et al 1980), power supplies (Ruggles and Pay 1982), high-voltage displays (Fujii et al 1981), and power circuits (Shackle and Pospisil1983); and (Wlldi and Chow 1984).…”
