1. A full-wave bridge rectifier isolated from the 220 V rms power line by a transformer. Assuming the diode voltage drops are 0.7 V. i. What turns ratio should the transformer have in order to produce an average current of 1 A in a 10 Q load? ii. What is the average current in each diode under the conditions of (i)? iii. What minimum PIV rating should each diode have? iv. How much power is dissipated by each diode?
