Question:
The working principle of SMPS is based on
The working principle of SMPS is based on
Show Hint
SMPS uses switching (chopper action) for efficient power conversion.
Updated On: Jul 2, 2026
- Integral control principle
- Frequency control principle
- Chopper principle
- Phase control principle
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
SMPS = Switched Mode Power Supply.
Step 1: Basic idea Converts power using high-frequency switching.
Step 2: Switching action Turns ON/OFF rapidly like a chopper circuit.
Step 3: Voltage control Output controlled by duty cycle.
Step 4: Efficiency Higher efficiency due to switching operation.
Step 5: Conclusion \[ \boxed{\text{Chopper principle}} \]
Final Answer: \[ \boxed{(C)} \]
