Lab Report 5 elec

Q1 a. Consider you have to choose b/w the Full-Wave Bridge Rectifier (FWBR) & Center-Tapped Full Wave Rectifier (CT-FWR) in one of your semester Lab projects. (1) Discuss the advantages of FWBR over CT-FWR which will justify, why to select the FWBR.

Part B Required

past exam paper that doesn't have answers, so just need help with the working out rather than getting an answer.

A rectifier is an arrangement of diodes connected in a bridge circuit. It provides the same polarity of output voltage for any polarity of the input voltage which is to be transformed.  1. Sketch circuit diagrams for your design of two different types of rectifier.   2. Sketch Voltage vs. Time diagrams for the input and output voltages based on your circuit diagram from ( Q1).  3.  If it is necessary to improve the DC output voltage, which type of component may be used and where should it be included in the circuit? (Show this in your diagram).  4.. Please List key issues when you select diodes for this application.

A half-wave rectifier is needed to supply 15 VDC to a load that draws an average current of 250 mA. The peak-to-peak ripple is required to be 0.2 V or less. a) What is the minimum value allowed for the smoothing capacitance? b) What if a full-wave rectifier is needed?

The four diodes used in a bri dge rectifier circuit have forward resistances which may be considered constant at 12 and an infinite reverse resistance. The alternating supply voltage is 240 V r.m. s. and resistive load is 48 Q. Calculate (i) mean load current |(i i) rectifier efficiency and |(i i i)power dissipated in each diode.

Q/ A single-phase controlled rectifier bridge consists of one SCR and three diodes feed R-load:a) Draw the circuit diagram of this bridge rectifier.b) Sketch output voltage waveform for a firing angle α for the SCR and hence obtain an expression for the average output voltage under the assumption of constant current. Show the conduction of various components as well.c) Draw waveforms of current through Tl, D1, D2 and D3 assuming constant load current.d) For an AC source voltage of 230 V, 50 Hz and firing angle of 45°, find the average output current and power delivered to 100Ω resistor.

the source voltage is 240√2 sin (2 50t) V, R = 10 ohms, and L = 50 mH. Calculate i. the mean and rms values of the load voltage, Vo and Vrms the mean value of the load current, I. ii. iii. the current boundary conditions, namely lolz and I02 iv. the average freewheels diode current, hence average rectifier diode current V. the rms load current, hence load power and supply rms current the supply power factor. vi. iDI io Vs D₂ iD2 D₁ R + Vo

4. Please I want a solution of this question with all details. Many Thanks Note: It is preferable to solve by typing.

The output voltage waveform of a single-phase half-wave controlled rectifier supplying RL load is shown in the figure below. Determine Vorms, Voavg, Ioavg, and output current equation as a function of time at the conducting period, if you know that the supply voltage to the rectifier is 220, 60 Hz, and the load resistance and inductance are R=102, L= 10 mH Vout (volt) 0.019444 0.025 0.02731 Time (sec)
