Power devices are required for systems that operate over a broad spectrum of power levels and frequencies as discussed in the textbook1. The wide range of operating frequency for these applications was illustrated in Fig. 1.1. Another classification for the applications that is useful is based up on the operating voltage level as shown in Fig. 9.1. At lower voltages (< 100 voltages), a large number of power rectifiers are needed for computer power supplies and in automotive electronics. Rectifiers with larger voltage ratings are required for many other applications, such as motor drives, shown in the figure.
