What I’ve done in this summer
• Learned the method to decide optimal size• Partial implementation of control circuit.• Combine boost converter with front end
circuit.(Alec)
Method to Find Optimal Size
• Find the intersection of loss and Cvsquare

Problems
Integration
• It works. 94% of power transfer on my circuit. Yet, not optimal.
• Control circuit’s loss was not included.
Conclusion
• Even though spending much time on wrong device, I figured out the whole structure, and the way to implement my goal.
• Modify only a small part of the circuit, v2 can be complete.
