A transformer is delivering power to a 300-Q resistive load. To achieve the desired power transfer, the turns ratio is chosen so that the resistive load referred to the primary is 7,500 Q. The parameter values, referred to the secondary winding, are:
13.24 Calculate the transformer ratio of the transformer in Problem 13.23 when it is used as a step-up transformer.
13.25 A 2,300/240-V, 60-Hz, 4.6-kVA transformer is designed to have an induced emf of 2.5 V/turn. Assuming an ideal transformer, find
r1 = 20 Q L1 = 1.0 mH Lm = 25 mH
a. The numbers of high-side turns Nh
r2 = 20 Q L2 = 1.0 mH
Core losses are negligible.
a. Determine the turns ratio.
b. Determine the input voltage, current, and power and the efficiency when this transformer is delivering 12 W to the 300-Q load at a frequency f = 10,000/2π Hz.
