What is the primary function of a freewheeling diode connected across an inductive load in a single-phase semi-converter?
- 1It forces the DC load current to become highly discontinuous.
- 2It prevents the load voltage from becoming negative, thereby keeping the DC load current continuous.✓
- 3It increases the reactive power drawn from the source.
- 4It assists regenerative operation with a DC motor load.
Correct answer
It prevents the load voltage from becoming negative, thereby keeping the DC load current continuous.
