Challenge Problems
Push your limits with challenges.
Question 1
A design team needs to evaluate two different MOSFETs for a PWM application. MOSFET A has a switching loss of 1.5W and conduction loss of 5W at a given frequency. MOSFET B has a switching loss of 2W but a lower conduction loss of 2.5W. Which one should they choose for efficiency and why?
💡 Hint: Compare overall power dissipation to conclude efficiency.
Question 2
Explain how rise time and fall time affect the efficiency of a high-frequency power supply circuit. Provide examples involving specific components.
💡 Hint: Consider real-world component datasheets for specific rise and fall times.
