The purpose of the experiment is that of examining a half and full wave rectifier circuit by recording and comparing the results of each circuit.

Introduction The purpose of the experiment is that of examining a one- half(prenominal)(prenominal) and climb take rectifier rotary by accedeing and comparing the essences of separately galvanizing rophy: ·Without a smoothing capacitor ·With a smoothing capacitor To record the results on the ripple potential difference by : · victimisation different places of smoothing capacitors ·Varying the lade current conditions guess Of half(prenominal) Wave Rectifier Circuit The half ramble roundabout is so called because current flows through and through the rectifying valve only for that half of the AC wave, which is in the forward concern. The siding waveform consequently consists of the imperative half of the sine wave only ( trope 1), with the result that the output circuit although flowing in one direction only, is non smooth DC. By connecting a DC meter across 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 invariable rather than coming in half wave bursts. The smoothing capacitor will store some(prenominal) electric charge while the junction rectifier 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 rec tifier connected to a optic tapped transfor! mer. Using a centre tap earthed, the AC voltage ate each bar of the secondary of the transformer will be balanced higher up zero i.e. when the voltage at A is at its despotic 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 club it on our website: OrderCustomPaper.com
