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.
