In current commutated DC-DC choppers, the voltage spike appears across the load when_____________?
Correct answer: C. Both A. and B.
- A. Voltage across the commutating inductances collapses
- B. The capacitance voltage adds to the supply voltage
- C. Both A. and B.
- D. None of these
Explanation
During current commutation, the commutating inductance voltage collapses while the charged commutating capacitor can add its voltage to the supply. Their combined effect produces the voltage spike across the load.
