Tata Advanced Systems System Integration Engineer Interview Questions and Answers

A 3 phase inverter converter diagram converts DC power to AC power with 3-phase output.

• The converter has 6 switches that control the flow of current.

• The DC power is fed into the converter and is converted into 3-phase AC power.

• The output voltage can be controlled by adjusting the pulse width modulation (PWM) signals.

• The converter can be used in various applications such as motor drives, renewable energy systems, and UP...read more

An induction motor works by using electromagnetic induction to create a rotating magnetic field.

• The stator creates a rotating magnetic field

• The rotor is made of conductive bars and currents are induced in them

• The interaction between the stator and rotor currents creates torque

• The speed of the motor is determined by the frequency of the power supply

• Induction motors are commonly used in industrial applications

A full wave rectifier is an electronic circuit that converts AC voltage to DC voltage.

• A full wave rectifier uses four diodes to convert AC voltage to DC voltage

• The output of a full wave rectifier is smoother than that of a half wave rectifier

• The efficiency of a full wave rectifier is higher than that of a half wave rectifier

• Examples of full wave rectifiers include bridge rectifiers and center-tapped rectifiers
