For a step-down chopper feeding an RLE load, which set of parameters is required to determine the minimum value of duty cycle (α') needed to maintain continuous conduction?
- 1The load resistance (R) only
- 2The peak load current (Imax) only
- 3The load back EMF (E) only
- 4Switching frequency (f), duty cycle (α), supply voltage (Vs), and load parameters (R, L, E)✓
Correct answer
Switching frequency (f), duty cycle (α), supply voltage (Vs), and load parameters (R, L, E)
