Most electronic systems, like HDTVs, DVD/CD players, and computers,
need a dc voltage to work properly. Since the power-line voltage is
alternating, the first thing we need to do is to convert the ac line
voltage to dc voltage. The section of the electronic system that
produces this dc voltage is called the power supply. Within the power
supply are circuits that allow current to flow in only one direction.
These circuits are called rectifiers. This chapter discusses rectifier
circuits, filters, clippers, clampers, and voltage multipliers.
