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 1A in a 10 2 load? ii. What is the average current in each diode under the conditions of (i)? iii. What minimum PIV rating should each diode have?
