EECS 314 Fall 2006 HW 07 Problem 1 Student's name ___________________________ (Last name, first name, IN INK) Part 2 Consider the circuit with the same source and the same load, connected through a transformer, which is specially chosen to achieve maximal power transfer. The transformer has n 1 = 1000 turns in its primary coil. Calculate the number of turns n 2 in the secondary coil and the average power P MAX in watts transferred to the load. Calculate the ratio of powers P 1 / P MAX Part 3 Assume that you found a transformer that has 300 turns in one coil and 600 turns in the other coil, and decided to use it in this circuit for impedance matching. Which coil would you use as the primary? What average power P 3 in watts is transferred to the load in a circuit with this transformer? Calculate the ratio of powers P 3 / P MAX Write a brief conclusion on whether this transformer is a good replacement for the perfect transformer discussed in Part 2 (see Hint D above). Write your results below.
