A charger supplies 100 W at 20 V for charging the battery of a laptop. The power devices, used in the converter inside the charger, operate at a switching frequency of 200 kHz. Which power device is best suited for this purpose?
- IGBT
- Thyristor
- MOSFET
- BJT
Correct answer: MOSFET
Solution
MOSFETs are ideal for high-frequency applications like this one due to their fast switching capabilities and low on-resistance, making them efficient for power conversion at 200 kHz.
