in most power electronic applications, the power input is in the form of a 50- or 60-hz sine wave ac voltage provided by the electric utility, that is first converted to a dc voltage. in most applications, the rectifiers are supplied directly from the utility source without a transformer. a large capacitor is usually connected as a filter on the dc side. the simple diode rectifiers may not be allowed into the utility. 5-4

in this chapter, rectifiers with single-phase and threephase inputs are discussed. the diodes are assumed to be ideal in the analysis of rectifiers. the electromagnetic interference (emi) filter at the ac input to the rectifiers is ignored.
