INVESTIGATE FULL WAVE SINGLE PHASE CONTROLLED RECTIFIER Objectives: • To investigate the operational of full wave single-phase controlled rectifier with different load. • To measure and record all current and voltage signals before conversion and after conversion when the rectifier is connected to resistive load and controlled at various firing angle, a. To observe the effect on the rectifier circuit operation when adding an inductor to resistive load. • To verify by calculation the measured values in experiment. • To verify by simulation the input and output waveforms obtained in experiment. Equipment: LN trainer kits, Oscilloscope, Multimeter, 270 Resistor and 0.3 H Inductor. TIK Tz Load AC Vout 1 T4 XTs Figure 1: Single phase full wave diode rectifier circuit
Task 1: 1. On the LN training kit construct the circuit shown in Figure 1. 2. Use Phase 32 software to run simulation on the constructed circuit in 1. Adjust the firing angle, a of rectifier switches to a value between (30° to 100°). 3. With reference to step 2, record: I. The computer displayed waveforms of current and voltage for both input and output signals. ii. The rms and the peak value of input voltage and current waveforms in 3(1). Compare the readings with meter readings at the trainer. ii. The rms, average/mean and peak value of output waveforms voltage and current in 3(1). Compare the readings with output meter readings. 4. Verify the obtained waveforms in 3(1), 3(i), and3(ii) by simulation using an appropriate circuit simulation software (PSim, Mathlab/Simulink, MultiSim, PSpice ect). 5. Verify all the measured values from the meter by applying relevant mathematical equations. 6. Present all results in table form. Task 2: 1. Add an inductor in series with the resistor in the circuit in Task 1. 2. Repeat procedures 2 to 6 in Task 1. Task 3: 1. Replace the inductor in the circuit in Task 2 with a DC motor. 2. Adjust switch firing angle, a to three different values within range (30° to 100º). 3. Record speed of the DC motor in table form.
Task 4: Produce a standard format of report that covers Task 1 and Task 2 and Task 3 of the experiment. The report must include the following items: i. Introduction ii. Tables of experimental results, simulation results and calculation results ii. Simulation circuit diagram and waveforms iv. Results analysis/discussion v. Conclusion
