Electrical Engineering XYZ MCQs
In industries which electrical braking is generally preferred:
- Plugging
- Regenerative braking
- Dynamic braking
- None of these
Correct answer: 2. Regenerative braking
Explanation: Regenerative braking takes the concept of dynamic braking one step further, in converting the DC bus over-voltage into usable AC power to be placed back on the AC line for other AC devices to use. Rather than regulate DC bus voltage via a shunt resistor switched on and off by a special transistor, a regenerative drive manages the same task by augmenting the bridge rectifier diode array with a set of six more power transistors, then switching those transistors on and off synchronously with the line voltage (the AC power source).
