Question 1
What is the main formula for calculating dynamic losses in MOSFETs?
- P_{sw} = (V_{DS} * I_D) / R_{DS(on)}
- P_{sw} = 1/2 V_{DS} I_D (t_r + t_f) f_{sw}
- P_{sw} = I_D^2 * R_{DS(on)}
💡 Hint: Focus on the parameters influencing dynamic losses.
Question 2
True or False: Increasing the rise time t_r can help reduce dynamic losses.
- True
- False
💡 Hint: Think about how longer transitions affect power.
