2. A current-type PWM rectifier supplied from a 230 V line generates 260 V dc at its output. Consider a switching cycle within which the reference vector of input currents has the phase angle of 80. The switching frequency is 5 kHz. Find and sketch (not necessarily to scale) the switching pattern of the rectifier, that is, waveforms of switching variables a through c'. HINT: Assume that the maximum available output voltage of this type of rectifier equals 92% of the peak line-to-line supply voltage. 2.
