DC Machines

DC Generator Characteristics

As shown by equation 1, the terminal voltage of the separately excited DC generator would be expected to … Read More

DC Generator Operation

When operated as a generator, the armature of the DC machine is driven by a prime mover. As … Read More

Voltage Source Inverters (VSI) Operation | VSI Working Principle

The voltage source inverter is a somewhat older design and less expensive to implement. Various implementations of the … Read More

Variable-Frequency Drive Working Principle | Variable-Speed Induction Motor Drive

The induction motor is basically a constant-speed motor, as it operates within 3% of the synchronous speed, which … Read More

Pulse Width Modulated Inverter | PWM Inverter
