Introduction The purpose of the experiment is that of examining a one- one-half(prenominal) and climb sweep rectifier rotary by demoing and comparing the essences of separately galvanising rophy: ·Without a smoothing optical condenser ·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 hypothesis Of half(a) Wave Rectifier Circuit The half wheel circuit is so called because current flows done the rectifying tube only for that half of the AC wave, which is in the forward concern. The payoff waveform consequently consists of the commanding half of the sine wave only ( trope 1), with the result that the output circuit although flowing in one direction only, is not smooth DC. By connecting a DC meter crossways the load resistor in the half wave rectifier circuit the recorded voltage will be less than half that of the r.m.s. (root me an 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 never- depoting rather than coming in half wave bursts. The smoothing capacitor will store some(prenominal) electric charge while the rectifying valve 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 spunk t apped transformer. Using a centre tap earthe! d, the AC voltage ate each end of the secondary of the transformer will be balanced higher up zero i.e. when the voltage at A is at its dictatorial 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:
