Answer #1

For three-phase, Full-wave, Semi-controlled rectifier,
sketch the waveforms for following at firing angle Alpha = 90 and
over-lap angle Gama = 10
Gama of the diode = 10
Gama of the Thyristor=5
a- The positive and negative voltage relative to neutral.
b- The input current for phase (a)
Gama diode 10
Gama Thyristor 5
Sketeh a and b

For the transformer, sketch the input and output waveforms given
a sine wave input voltage. Note: the vertical axis represents
voltage and the horizontal axis represents time. Compare and
contrast the amplitude, shape, phase, and period. Repeat for a
square wave.

1. Design a full-wave bridge rectifier power supply to deliver
an average voltage of 9V with a peak-to-peak riple of 2V to a load.
The average load current is 100 mA. Assume that ideal diodes and
60-Hz ac volatage sources of any amplitudes needed are avaialable.
Draw the circuit diagram for your design, Specify the values of all
components used.
2. Repeat Problem 1 with 2 diodes and out-of-phase voltage
sources to form a full-wave rectifier.

In a full-wave rectifier with two diodes, calculate
a) The value of V0, I0
b) Vr and R.F
c) Draw the complete circuit with proposed data and calculated data
Consider that the voltage of the secondary of the transformer is 30 V, the diodes are IN4003, the capacitor C1 is 1000 Nf and Rl is 100 Ω

In a full wave rectifier does the positive half cylce produce an
output dc voltage or is the ouput dc voltage only produced at the
negative half cycle ?

Design a full-wave bridge rectifier circuit to deliver 10
volts DC with less than 0.1 volt peak-to-peak ripple into a 1 k
load. Assume a 60 Hz input sin wave.

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...

I want to design a full wave rectifier with bandwidth 50mHz and
gain 1. What is the circuit and component values? What type of
amplifier should I use?

Draw the circuit for a three-phase full-bridge non-isolated
inverter. Describe how the converter works using switching
waveforms. Include a description of two different control
strategies using PWM and square-wave phase difference methods.
Clearly define the amplitude and frequency modulation indexes in
the PWM method. Discuss and calculate the rms phase and line
voltages when the DC input voltage is 400V.

Write a Report on the following –
1) Describe waveform characteristics for sinusoidal
waveforms
2) What is a Diode? Explain forward and reverse biased
characteristics of a diode with circuit diagrams.
3) What is a rectifier? Explain half wave and full wave
rectifier with circuit diagrams.
