Vem Technologies Electrical Engineer Interview Questions and Answers

Armature voltage control involves changing the voltage applied to the armature of a DC motor to control its speed, while field control involves changing the field current to control the motor's speed.

• Armature voltage control adjusts the voltage applied to the armature winding of a DC motor to control its speed

• Field control adjusts the field current in the motor to control its speed

• Armature voltage control is more commo...read more

A boost converter is a type of DC-DC converter that steps up the input voltage to a higher output voltage.

• Use a switch (usually a MOSFET) to control the energy flow from input to output

• Include an inductor to store and release energy

• Add a diode to allow current flow in one direction

• Use a capacitor to smooth out the output voltage

• Implement a control circuit to regulate the output voltage
