Introduction The purpose of the experiment is that of examining a one- fractional(prenominal) and climb rock-and-roll rectifier rotary by go intoing and comparing the essences of separately galvanic rophy: ·Without a smoothing capacitance ·With a smoothing capacitor To record the results on the ripple potential difference by : · use different places of smoothing capacitors ·Varying the lade current conditions scheme Of half(a) Wave Rectifier Circuit The half shake go is so called because current flows by the semiconductor rectifying tube only for that half of the AC wave, which is in the forward concern. The turnout waveform consequently consists of the imperative half of the sine wave only ( bod 1), with the result that the output circuit although flowing in one direction only, is not smooth DC. By connecting a DC meter crosswise the load resistor in the half wave rectifier circuit the recorded voltage will be less than half that of the r.m.s. ( root mean square) value of the AC voltage applied to the rectifier. Fig 1 Half Wave Rectifier Circuit By selecting a suitably large value of capacitor, current flow through the load resistance weed be made unremitting rather than coming in half wave bursts. The smoothing capacitor will store some(prenominal) electric charge while the diode is conducting; this releases this charge to try current flow while the diode is not conducting. (Fig 1b).
Fig 1b sound wave rectifier circuit with smoothing Theory of Full Wave Rectifier Circuit Fig2 shows a full wave rectifier connected to a focus on tapped transformer. Using a centre tap earthed, the! AC voltage ate each quit of the secondary of the transformer will be balanced higher up zero i.e. when the voltage at A is at its exacting peak, the voltage at B will be at its negative peak and vice versa. When the winding end marked A is positive, If you want to get a full essay, baseball game club it on our website:
