Inverter is a device which convert a DC input supply voltage into symmetric AC voltage of desired magnitude and frequency at the output side. It is also know as DC-AC converter.
Ideal and practical inverter have sinusoidal and no-sinusoidal waveforms at output respectively.
If the input dc is a voltage source, the inverter is called a Voltage Source Inverter (VSI). One can similarly think of a Current Source Inverter (CSI), where the input to the circuit is a current source. The VSI circuit has direct control over ‘output (ac) voltage’ whereas the CSI directly controls ‘output (ac) current.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Introduction:
The alternating current has
several advantages over direct
current is that,
Alternating Current can be easily
transferable from low to high
voltage
Alternating voltage can be raised
or lowered as per requirement by a
static device called
TRANSFORMER
3. What is a transformer?
A static piece of apparatus by means of
which an electrical power is transferred
from one alternating current circuit to
another electrical circuit
There is no electrical contact between
them.
The desire change in voltage or current,
without any change in frequency.
Symbolically the transformer
Denoted as,
5. Structure of Transformer:
The transformer consists of 2 inductive coils,
they are electrically separated but linked
through a common magnetic circuit. They have
high mutual induction
One of them is connected to a source of
alternating voltage. This coil in which electrical
energy is fed with the help of source called
primary winding(P).
The other winding is connected to a load. The
electrical energy is transformed to this winding
drawn out to the load. This winding is called
secondary winding(S).
6. The primary & secondary coil wound on
a ferromagnetic metal core. The
function of the core is to transfer
the changing magnetic flux from the
primary coil to secondary coil.
The no. of turns plays an important
role in the function of transformer.
7. Working Principle:
The transformer works in the principal of
mutual induction.
“ The principle of mutual induction states
that when 2 coils are inductively coupled
and if the current in coil change uniformly
then the e.m.f induced in the other coil.
This e.m.f can drive a current when a
closed path is provided to it.”
When an Alternating current flows in
Primary coil, a changing magnetic flux is
generated around the primary coil.
8. The changing magnetic flux is transferred to
the secondary coil through the iron core.
The changing magnetic flux is cut by the
secondary coil, hence induces e.m.f. in the
secondary coil.
Now if load is connected to a secondary
winding, this e.m.f. drives a current through it.
The magnitude of the output voltage can be
controlled by the ratio of the no. of primary
coil & secondary coil.
“The frequency of mutually induced e.m.f as
same that of the alternating source which
supplying energy to the primary winding”
10. Construction:
There are 2 basics of transformer contraction.
1. Magnetic Core
2. Windings or coils
MAGNETIC CORE:
The core of transformer either square or rectangular
type in size
Core is made of laminations. Because of laminated core
type constructions, eddy current losses get minimize.
Generally high grade silicon steel laminations (0.3 to 0.5
mm) are used.
These lamination are insulated from each other by using
insulation like varnish or thick paper.
11. Windings:
Conducting material is used in the windings of
the transformer.
The coils used are wound on the limbs and
insulated from each other.
The 2 different windings are wounds on 2
different limbs i.e. primary on 1 limbs while
secondary on other limb in the basic
transformer.
The leakage flux increase which affects the
performance and efficiency of transformer.
To reduce the leakage flux it is necessary that
the windings should be very close to each other
to have high mutual induction.
12. Core type Construction:
In the core type 1 magnetic circuit &
cylindrical coils are used.
These coils are mechanically strong.
Normally L & T shaped laminations are
used.
Commonly primary winding wound on 1 limb
while secondary on the other but
performance will be reduce.
To get high performance it is necessary
that the 2 windings should be very close to
each other.
13.
14. Shell type construction:
In the shell type 2 magnetic circuit are used.
The windings is wound on central limbs.
For the shell type each high voltage winding lie
between 2 low voltage portion sandwiching the high
voltage winding.
Sub-division of windings reduces the leakage flux.
All the portions are insulated by paper.
Greater the no. of sub-divisions lesser the
reactance.
This type of construction is used for high voltages.
15.
16. Losses In Transformer:
In transformer, there exists 2 types of
losses.
1. Core losses
2. Copper losses
Core losses: It has also 2 types of losses.
1. Hysteresis loss: During magnetization and
demagnetization, due to hysteresis effect some
energy losses in the core called hysteresis.
2. Eddy current loss: The leakage magnetic flux
generates the e.m.f. in the core produces
current is called eddy current loss.
17. Copper losses
The copper losses is due to power wasted
in the form of I2r due to resistance of
primary and secondary. The magnitude of
copper losses depend upon the current
flowing through these coils.
“The iron losses depend on the supply voltage
while the copper losses depend upon the
current. The losses are not dependent on
the phase angle between the voltage and
current.”
18. Types of transformer:
Step up transformer
No. of secondary
windings are greater
than the no. of primary
windings(Ns> Np).
It converts low
alternate voltage to
high alternate voltage.
This type of
transformer is called
step up transformer.
Step down transformer
No. of primary windings
are greater than the no.
of secondary windings
(Np> Ns).
It converts high
alternate voltage to low
alternate voltage.
This type of
transformer is called
step down transformer.
19.
20. Ideal V/S Practice
Transformer:
A transformer is said to be ideal if it satisfies
the following properties, but no transformer is
ideal in practice.
It has no losses
Windings resistance are zero
There is no flux leakage
Small current is required to produce the
magnetic field
While the practical transformer has winding
resistance, some leakage flux and has little bit
losses.
21. Can a transformer step up or step down
the DC current or voltage?
The DC supply cannot be used for
transformer.
Because the transformer works on the
principle of mutual induction, for which the
current in the coil changes uniformly. If
DC supply is applied the current does not
change uniformly due to constant supply
and transformer will not work.
“The DC supply may cause the transformer
to damage permanently”
22. Applications & Uses:
The transformer is used in Television and
photocopy machines.
The transformer(ballast transformer) are also
installed in fluorescent tube lights.
The transmission & distribution of alternating
power is possible by transformer.
Simple camera flash uses fly back transformer.
Signals and audio transformer are used couple
in amplifier.
“Today transformer has become an essential part
of electronics engineering”
