Unformatted text preview: EE 2001 Fall 2008 Problem Set 5 Clipper Circuits a) Using only two devices, add a clipper circuit to the circuit diagrammed below that will limit the output voltage to the range -15 volts to +10 volts. Assume 0.6 volt forward diode drop and label all component values. b) If VIN can range from ~~20 volts to +20 volts, calculate R so that the current in the clipper branch does not exceed 10 mA. c) Repeat part b with a 1 k9 resistor placed across the output. Rectification Circuits Accurately plot im, im, and i0 in the full-wave rectifier circuit diagrammed below. You may assume that these are ideal diodes. 0 DIIIIIIIIIIIHIIIID “me IIIIIIBIIIIHIIIIII IIIIIIIIIIHIIIIIII IIIIIIIIBHIIIIIIII "I'IIIIIIIIIIIIII II I AL 0 IIIIIIIHIIEIIIIIII fime IIIIIIIIIIIIIIIIII IIHBIIIIHEIIIIEIII 0 IIIIIIIHIIKIIHIIEI IIIIIIIIIIIIIIIIII time Diodes For the zener regulator circuit diagrammed below, find the maximum and minimum power dissipated in the 4 ohm dropping resistor and in the 12 volt zener diode. 49 + 4wattsmin 20VDCi4VDC 0 ”V A V0 8Wattsmax CAL/J4 W+V4mzj: (/ 3/1 2/ _ '- ' L/ ,, T , , {44.33; ‘I’ g/ 73/» — [ltd/3,4) $ij W/v)’ 27. ,zv/thg { gw ’ [dd/“X Loa/ ’ A p; : {,2 1/)(253/1) ~Zb’MA 3/7 9/ 0 Man/V Pfl_ . \l%/ Q»: 36w ' fc/ ’ , ( [Dz : 3.4 W 9 /$’JL ': (/W 0 /z : VM/ ...
