Explain the operation of 12-pulse full controlled rectifier by
sketching circuit schema and related waveforms and by giving the
fundamental equations. What are the advantages of that circuit?
Give the Vs and Vo waveforms of a three phase bridge controlled
rectifier. Draw different waveforms for angles 30,60,90,120 degrees
for each a resistive load and then a RL load. Clearly label period
in degrees on X axis.
For three-phase, Full-wave, Semi-controlled rectifier, sketch
the waveforms for following at firing angle Alpha = 90 and over-lap
angle Gama = 10
a- The positive and negative voltage relative to neutral.
b- The input current for phase (a)
The controlled full wave rectifier is connected to the grid. The
rms grid voltage is 230 Volt at 50 Hz. 24 Volt battery will be
charged with 15A. An inductor, which is series connected to the
battery, is used to limit the current ripple. Only The second
harmonics of the output voltage is taken into account. The inductor
R/L ratio is 50. The current ripple is allowed to be 4 amp peak to
peak. Determine the firing angle and R...

Derive the expressions of the average load voltage and current
in single-phase full-wave controlled rectifier (bridge rectifier)
and resistive load. Draw the waveforms of supply voltage, output
voltage, output current and thyristor current.
In a single-phase full-wave controlled rectifier (bridge
rectifier) and resistive load, it is desired to get an average load
voltage of 50 V. Determine the firing angle if the ac supply
voltage is 150 V. If the average load power is 300W, calculate the
average load...
