Extracted text: Análisis de rectificador onda completa Consider the capacitor-filter rectifier circuit as shown in Figure 1. The input is a single-phase source that is derived from a 220 Vrms mains. Tasks for analysis: (a) Rig up the circuit as shown in Figure land plot V andi versus time. (b) Why is there ringing on the current wave-form? (c) What is the series impedance of the circuitệ (d) Plot V and V. versus time. What is the ripple? How does ripple depend on load, capacitor C; and frequency of input wave-form? (e) Measure the current and voltage waveform across the rectifier diode. (f) Estimate the average and ms currents through the rectifier diode, Calculate the diode power dissipation. (g) What should be the peak current rating of the diode? (h) Change the initial charge voltage on the capacitor Cr. What is the effect on the input surge current? (i) Change the phase angle of the input V, at start up. Observe the effect on current i. What happens and why? 1) Under whaf conditions do you get maimum peak current to flow through the diodes? (k) Measure the input voltage and current and estimate the power factor. (1) What is the effect of change in Cr value on the input current and power factor? (m) Choose a suitable value for R and construct a simulation model in LTspice and verify your analytic results.
