The circuit diagram below shows a full-wave bridge rectifier, and it includes a filter capacitor. If the circuit is powered by 70 Hz mains, and the load resistor is 2600 Ω, calculate a suitable value for the capacitor. If the peak value of the rectified voltage = 400 volts, determine the ripple voltage. Select one: C = 172 nF; Vripple = 45 volts C = 47 μF; Vripple = 1.3 volts C = 0.62 μF; Vripple = 22 volts C = 2 μF; Vripple = 4.0 volts C = 27 μF; Vripple = 40 volts
![Consider the full-wave diode rectifier circuit shown in the figure below. Assuming the input voltage is VAC = 170 sin(120πt) the conduction angle of the diode is 32∘, and the load resistance RL = 500 Ω, and the capacitor CS = 100 μF. We assume that all components are ideal and neglect the voltage drop across the diodes. {For the questions below, please only state the value. No need to include the units in your answers}. (a) Estimate the peak-to-peak ripple voltage in the output voltage VR. [2 marks] (b) The average voltage. [2 marks] (c) The RMS voltage. [2 marks] (d) The form factor. [2 marks] (e) If the ripple voltage across the load resistance RL must not exceed 1 V peak to-peak, calculate the value of smoothing capacitance required. You may assume that the capacitor provides current to the load for each complete cycle of the rectified voltage. [4 marks]](https://www.doubtrix.com/uploads/editor/0294629005gsMjwksRCG.jpg)
