Re-submission of
question.
Consider the full-bridge single-phase inverter with input voltage
equal to 200V. This inverter is controlled by sinusoidal PWM
technique with amplitude modu- lation
index equal to 0.5 to generate a 3- level half-wave symmetry
waveform with frequency equal to 50
Hz.
e)Calculate the amplitude of fundamen- tal
frequency.
f) Draw the waveforms of refrence and
carrier
signals.
g) Obtain the waveform of output
voltage.
h)Design the trigger signals of switches. Thanks for
your help.
Question 5
a) Draw the circuit of a Three-phase bridge inverter using a
Y-connected load and explain its operation using 180 degree
conduction clearly showing the gating sequence and the
corresponding output line voltages for each phase. (10)
b) For the Y-connected load determine the line to neutral
voltages for the three modes of operations. Draw the equivalent
circuits for each mode and then draw the phase voltage waveforms
for the 180-degree conduction. (7)
Using a wheatstone bridge, solve for Vout for quarter, half, and
full bridges and determine which one is most sensitive. Draw a
diagram showing how you would place your strain gauges on a beam
for each configuration. Discuss how you should use the right kind
of strain gauge with appropriate G values to maximize the
sensitivity.
Demonstrate in Multisim a full wave bridge rectification which
produces a negative voltage at the output. With input voltage set
as 10sin(80*pi*t). Take RL=5.7kΩ. Show the desired output in
oscilloscope with proper scaling. Also perform filtration with
capacitor having the value 50 uF.

An Uncontrolled Full-Wave full-bridge rectifier with
RL-Source load and Discontinuous load
current is to be designed based on the following assumptions and
constraints. Design the circuit
and calculate the parameters of the rectifier based on the
following assumptions and constraints.
Simulate the designed rectifier in PsPice and compare the simulated
and the calculated results.
a) The AC source is 220 V rms at 50 Hz. Vdc= 65 V, power absorbed
by the resistor is 360
W.
b) The AC source...

A solar Photovoltaic (PV) system consists of a PV panel, a charger controller, a battery, and an inverter. The manufacturer of the PV system guarantees 20 years of lifetime of the entire PV system with reliability of 0.90 at the end of 20 years. The failure rate of its major components is given in Table 1. To achieve the overall system reliability goal, we can add redundant units for each subsystem (see Figure 2). Note that System A is the...
