Techser Power Solutions Interview Questions and Answers

The parts of an inverter include DC input, power transistors, transformer, output filter, and control circuit.

• DC input: where the direct current is supplied to the inverter

• Power transistors: responsible for converting DC to AC

• Transformer: used to step up or step down the voltage

• Output filter: smoothens the output waveform

• Control circuit: manages the operation of the inverter

The formula for radiation of the day is based on the Stefan-Boltzmann law, which states that the total energy radiated per unit surface area of a black body is directly proportional to the fourth power of the body's absolute temperature.

• Radiation of the day is calculated using the Stefan-Boltzmann law: P = σAT^4

• P represents the power radiated per unit area, σ is the Stefan-Boltzmann constant, A is the surface area, and...read more

Optimize moisture content refers to adjusting the amount of moisture in a material to achieve the desired properties.

• Optimizing moisture content involves finding the right balance to enhance the quality and performance of a material.

• It is important in industries like agriculture, food processing, and construction.

• For example, in agriculture, optimizing moisture content in soil can improve crop growth and yield.

Types of cement include Portland cement, white cement, rapid hardening cement, and low heat cement.

• Portland cement is the most common type used in construction.

• White cement is used for architectural purposes and to create colored concrete.

• Rapid hardening cement sets quickly and is used in projects with tight deadlines.

• Low heat cement generates less heat during hydration and is used in large concrete structures.
