A rectifier circuit with a filter at its output can be used to produce a DC voltage from an AC input. With proper design, the ripple voltage at the output. V, can be made small enough to meet the requirements for many applications. Such a circuit is usually the first stage of all linear DC power supplies. The filter can simply be a capacitor, which, by taking into account the load resistance. will form a low pass filter. To have small ripple voltage at the output, large filtering capacitors are needed. Therefore, electrolyte capacitors are often used for the filter. A half-wave rectifier with output capacitor is shown in Figure 5. What is the formula to calculate the output ripple voltage to the circuit parameters? V =____ Vin We want to use this circuit to convert a lkHz, 8V peak-to-peak sine wave (0 DC) to a DC voltage with a maximum ripple of 0.25V. What is the required value of Cr if the load resistance is 3.3kQ? Cp= Vin o #6 CF ww1. RL Vout Figure Rectifier with filtered output.
