For the circuit shown above let vs 10 sin 377t V Each diode

For the circuit shown above, let v_s = 10 sin 377t V. Each diode is to be modeled as a piece-wise linear device with the following parameters: V_o = 0.7V r_d = 26ohm Sketch v_s and v_o as a function of time. Calculate the ripple voltage of v_o and determine what percentage it is of the peak output voltage.

Solution

It is helpful to calculate the ripple voltage waveform\'s parameters after you would like to feature a regulator, so you\'ll be able to confirm that the troughs/valleys/minima of the ripple voltage wave shape can ne\'er excite the regulator\'s dropout region, i.e. so the regulator\'s Vin-Vout is rarely but its dropout voltage specification, wherever the minimum Vinis that the ripple voltage waveform\'s minimum voltage. therefore do not solely wory concerning the ripple voltage waveform\'s relative amplitude. conjointly calculate it\'s DC (average) level and its most and minimum as absolute voltage levels.

Note that you just would wish to use worst-case AC Mains variation for that (\"voltage regulator vs ripple\" calculations), or a minimum of 100% low AC Mains voltage if you do not have actual information for it. you\'ll be able to conjointlytake electrical device regulation into consideration, that typically helps mitigate things a bit
