KLUNIVERSITY, VADDESWRAM DEPARTMENT OF ELECTRONICS AND COMMUNICATION ENGINEERING ELECTRONIC DEVICES AND CIRCUITS (ECC 202)-Tutorial 1 1. A HWR is supplied from a 230 v,50 Hz supply with a step down ratio of 3:1 to a resistive load of 10K .The diode forward resistance is 75 Ω while transformer resistance is 10Ω.Calculate maximum, average, RMS values of current ,DC output voltage, Efficiency of rectification and ripple factor 2. (A) Assume an ideal diode.calculate the dc output voltage for the network shown below fig repeat the part (a) if the diode is replaced by a Si diode, having cut in voltage of 0.7v.neglect diode forward resistance. 3. A HWR with load resistance 1k is given an input of 10V peak from step-down transformer. Calculate DC voltage and load current for ideal and silicon diode. 4. A voltage V=300 cos 100t is applied to a half wave rectifier with load resistance of5 K Ω. The rectifier may be represented by ideal diode in series with a resistance of 1KΩ.calculate, 1. I max 2.DC power,3. AC Power, 4.Recification efficiency,5. Ripple Factor

"Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
