Lesson -13 - nptelDraw the circuit diagram and waveforms associated with a three phase fully
controlled bridge converter. ? Find out the average, RMS valves and the harmonic
spectrum of the output voltage / current waveforms of the converter. ? Find out the
closed form expression of the output current and hence the condition for
continuous ...8 Per Unit Calculations - nptelAs stated earlier, transformers of various sizes, ratings, voltage ratios can be
seen being used in a power system. The parameters of the equivalent circuits of
these machines also vary over a large range. Also the comparison of these
machines are made simple if all the parameters are normalized. If simple scaling

having the same capacitance, can be delta- or star-connected. When selecting
the connec- tion modality, it is necessary to keep into account that with delta
connection, each capacitance is subject to the supply line-to-line voltage, ...
