TechKing TV Interview Questions and Answers

Updated 21 Feb 2024

Q1. What is transformer?

Ans.

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

  • Transformers are commonly used to step up or step down voltage in electrical power distribution.

  • They consist of two coils of wire, known as the primary and secondary coils, wrapped around a core.

  • The primary coil is connected to a source of alternating current, which creates a changing magnetic field in the core.

  • This changing magnetic field induces a voltag...read more

Q2. What is inverter?

Ans.

An inverter is an electronic device that converts direct current (DC) to alternating current (AC).

  • Converts DC power to AC power

  • Used in solar power systems to convert DC electricity from solar panels to AC electricity for use in homes

  • Commonly used in uninterruptible power supplies (UPS) to provide backup power during outages

Q3. What is op amp?

Ans.

Op amp stands for operational amplifier, a type of electronic amplifier with high gain and differential inputs.

  • Op amp is a type of amplifier that amplifies the difference in voltage between its two inputs.

  • It has a very high open-loop gain, typically around 100,000.

  • Op amps are commonly used in signal conditioning, filtering, and mathematical operations in electronic circuits.

  • Examples of op amp ICs include the LM741, AD823, and TL072.

Q4. Type of transformer?

Ans.

Transformers are classified based on their construction and purpose, such as power transformers, distribution transformers, and instrument transformers.

  • Power transformers are used to step up or step down voltage for transmission and distribution of electricity.

  • Distribution transformers are used to supply lower voltage to end-users.

  • Instrument transformers are used for measuring voltage and current in power systems.

  • Other types include autotransformers, isolation transformers, a...read more

Q5. Type of inverter?

Ans.

The type of inverter used is a grid-tied inverter.

  • Grid-tied inverters are connected to the utility grid and do not require batteries.

  • They convert DC power from solar panels into AC power for use in the home or to be fed back into the grid.

  • Examples of grid-tied inverters include string inverters, microinverters, and power optimizers.

Q6. Transformer Design?

Ans.

Transformer design involves creating efficient and reliable electrical transformers for various applications.

  • Consider the desired voltage and current ratings for the transformer

  • Select appropriate core and winding materials for optimal performance

  • Design the transformer to minimize losses and improve efficiency

  • Perform simulations and testing to validate the design

  • Iterate on the design to meet specifications and requirements
