1. Semiconductor Switch Project1. Switch RealizationFor the Boost and Buck-Boost converters, replace the ideal SPDT switches with semiconductor SPST switches.
• Use MOSFET for switch operating quadrants Q1 or Q3
• Use Diode for switch operating quadrants Q2 or Q4
• Show all your work including SPST switch connections and how you determined operating quadrants.
2. Synchronous RectificationReplace all Q2 or Q4 diodes in your switch realization with MOSFETs. Draw and label your circuits.
3. Switch LossesGiven:1.Input voltage = 300 V2.Output power = 7500 WFor the Boost and Buck-Boost converters calculate conduction, switching, and total losses for a duty cycle range of 0.30 to 0.70 and a switching frequency range of 1 kHz to 100 kHz. For total losses, ignore leakage and parasitic losses. Use small ripple approximation for inductor current and capacitor voltage.
• Use the IPW65R018CFD7 (Datasheet on Canvas) MOSFET from Infineon for both SPST switches.
• Use maximum values, when available, for switch parameters from datasheet.
• Use at least ten equally spaced values for duty cycle range.
• Use at least ten equally spaced base-10 log values for switching frequency range.
• Show plots and tables for conduction, switching, and total losses. Use base-10 logarithmic scales if plotting against frequency.
4. Critical FrequencyFor the Boost and Buck-Boost converters, calculate the critical frequency for the above range of duty cycles. Ignore leakage and parasitic losses when calculating critical frequencies. Show plot and table for critical you show the graph table and plots
