Vritti Associates design and manufacture Power Transformers for a variety of power supply and power conversion applications. Power transformers may be designed in a wide variety of shapes and sizes.

Design requirements for a Power Transformer
Typical minimum requirements to be specified for a Power Transformer are

• Power rating in VA.
• Frequency usually 60 Hz.
• Number of primary windings.
• Number of secondary windings.
• Operating voltages levels.
• Operating current levels
• Operating frequency is needed for core calculations and wire sizing.
• Core material is selected for the known operating frequency or frequencies which is typically silicon steel laminations.
• Other Power transformer design considerations are space limitations and mounting technique.
• Lead terminations are also specified through the design of a Power Transformer.

Power transformer designs vary widely in terms of power rating, voltage and current levels (turns ratios), operating frequency, size, impedance, bandwidth (frequency response), winding and other parameters

A reliable power supply presupposes a sufficiently large supply system with high-performance transformers. The high quality standards set by VRITTI ASSOCIATES are appreciated throughout the world and these are applied to development, manufacture.
Power transformers up to 30 KVA class are regularly manufactured and supplied to the domestic/international markets as per various national/international standards. The high quality standards set up by the company are appreciated by our customers in India and abroad.
The design, manufacturing and test facilities have been approved to ISO9001:2008 Certification, and the high quality and attention give to customer’s requirements have resulted in  VRITTI ASSOCIATES being granted approval by a significant No. of International & national companies in the electronic & electrical Industries.

Toroidal Transformeroffer many advantages over a conventional laminated transformer.Toroidal has a round shape with no air gaps, and with the primary and secondary windings uniformly ditributed around the core, "locks in" the magnetic field and makes the toroidal transformer very quiet and efficient.

Toroidal Transformer, by meeting today"s requirements for smaller, more efficient, quieter and safer products, are being accepted in an increasing range of electronic and electrical equipment.With toroidal transformer smaller dimensions, lighter weight and low stray magnetic fields, you can build more compact, lower cost quality products without sacrificing performance.

A switched-mode power supply (also switching-mode power supply, SMPS, or simply switcher) is an electronic power supply unit that incorporates a switching regulator in order to provide the required output voltage. The switch mode transformer is used in conjunction with the switching regulator to form a switch mode power supply.
Switch mode power transformers are used extensively in electronic applications, usually within a switch mode power supply

Switching Mode Power Transformers, Basic Application CircuitsThe design of a switch mode power transformer will differ depending upon the type of circuit used. There are many variations of switching mode power supplies, but they can be narrowed down to three basic circuit configurations (each also has a mirrored configuration); Buck, Boost, and flyback. Be aware that the name for the Buck circuit varies from industry to industry and from person to person. It may also be referred to as an inverter, D.C. converter, forward converter, feed forward, and others. There are also unipolar and bipolar (push-pull) versions.

Toroidal inductors and transformers are electronic components, typically consisting of a circular ring-shaped magnetic core of iron powder, ferrite, or other material around which wire is coiled to make an inductor. Toroidal coils are used in a broad range of applications, such as high-frequency coils and transformers.
Toroidal inductors can have higher Q factors and higher inductance than similarly constructed solenoid coils. This is due largely to the smaller number of turns required when the core provides a closed magnetic path. The magnetic flux in a high permeability toroid is largely confined to the core; the confinement reduces the energy that can be absorbed by nearby objects, so toroidal cores offer some self-shielding.

Common Mode Chokes

• Common Mode Chokes are used when many electrical devices may be connected to the same power lines (or power supply lines) and therefore substantial electrical noise can exist on these lines.
• Line filters prevent excessive noise from being conducted between electronic equipment and the AC line. Noise is typically common to both lines and in the same direction.
• Common mode chokes are designed so that common mode current creates a magnetic flux (through mutual inductance) that adds to attenuate the CM noise signal.
• The normal (differential) mode currents create magnetic flux that ideally cancel each other out so the normal signal frequencies are not attenuated.
• Any inductance encountered by the differential signal is the result of imperfect coupling of the two coils.

Design requirements for a common mode choke

• It is typical for the inductance value of a common mode choke to be specified as a minimum requirement, thus insuring the crossover frequency is not shifted too high.
• The frequency range of the interfering signal should be given to allow proper calculation of the attenuation of unwanted signal noise in the design.
• Proper wire sizing is accomplished by specifying the voltage and current levels across and passing through the common mode choke.

Toroid InductorsToroid style common mode chokes are designed to provide the highest common mode impedance over the widest frequency range. These parts are ideal for any application requiring a high DC current bias and are well suited for use in switch-mode power supplies. Common mode chokes are most effective in filtering supply and return conductors with in-phase signals of equal amplitude. Differential mode inductors are available for filtering out-of-phase or uneven amplitude signals.
A Toroidal inductor is an inductor that is designed on a doughnut shaped core. Toroidal inductors offer small size, less leakage inductance and lower electromagnetic interference (EMI).

Design requirements  for  a Toroidal Inductors:
Typical minimum requirements to be specified for a Toroidal inductor design are:

• No load inductance in uH
• Full load inductance in u
• HDC Current in Amperes
• AC Current in Amperes peak to peak
• Operating frequency is needed for core calculations and wire sizing
• Core material is selected for the known operating frequency or frequencies.
• Other Toroidal inductor design considerations are space limitations and mounting technique.
• Lead terminations are also specified through the design of a Toroidal inductor.

Pulse TransformerA pulse transformer is a transformer that is optimized for transmitting rectangular electrical pulses--that is, pulses with fast rise and fall times and a relatively constant amplitude.

Principle 8 Operating Principles

• Magnetizing (No-Load) Current
• Voltage Drop
• Voltage-Time Product
• Kickback Voltage
• Secondary Load Current
• Effects of Winding Capacitance
• The Trailing Edge
• Pulse Distortion

The magnetic flux in a typical A.C. transformer core alternates between positive and negative values. The magnetic flux in the typical pulse transformer does not.  The typical pulse transformer operates in an “unipolar” mode (flux density may meet but does not cross zero.)
Pulse transformer designs vary widely in terms of power rating, inductance, voltage level (low to high), operating frequency, size, impedance, bandwidth (frequency response), winding capacitance, and other parameters. Designers try to minimize parasitic elements such as leakage inductance and winding capacitance by using winding configurations which optimize the coupling between the windings.

Volume Controls are constructed with the help of 100V transformers . This control switch comes with 11 volume steps (10 regulator steps and 1-zero position) and besides this , they have a E/M relay (24VDC) which makes emergency announcements possible even if control is at position "0".
