Purpose of the practical assignment 1 The purpose of the practical assignment is, by using the Simplorer, Power Word Simulator, Simulink, or any other Power Electronics, to build the model and perform simulation of a three-phase diode rectifier supplied from a 207.8 V three- phase source. 2. Requirements For this practical assignment the requirements are as following: Build the model of a three-phase diode rectifier with a resistive load of 1.5 considering the diodes are ideal (voltage drop across the diode to be nil) and internal impedance nil. As results for this requirement you should show: - The complete model • The graphs of the line voltage system, the de output voltage and current For the time axis you should select only 40 msec. • To present the measured de voltage and compare with the calculated one Build the model of a three-phase diode rectifier with a resistive load of 1.5 considering the voltage drop across the diode to be 2 V; the source impedance is nil. As results for this requirement you should show: • The graphs of the line voltage system, the de output voltage and current. For the time axis you should select only 40 msec. . For the "y" axis you should use the range between 150 V and 300 V. • Determine and quantify if there is any difference between the de voltage from 2.1 and this situation. . Using the knowledge about the influence of the diode voltage drop, calculate the de voltage and compare with the measured. Build the model of a three-phase diode rectifier with a load of 1.2 A series with an inductor of 3.82 m and considering the voltage drop across the diode to be 2 V. Introduce in series with each line of the three-phase source a leakage inductance of 38.2 pH. As results for this requirement you should show: - The graphs of the line voltage system, the de output voltage and current . For the time axis you should select only 40 msec from the steady-state situation. For the "y" axis you should use the range between 150 V and 300 V · Explain if there is any difference between the de voltage from 2.1 and the cition T.
• Explain if there is any difference between the de voltage from 2.1 and this situation. · Using the knowledge about the influence of the current commutation overlapping, calculate the de voltage and compare with the measured result. In a separate graph and using a proper zoom, show the influence of the current commutation/overlapping Note: . Each requirement should be presented in the same format. Use this electronic format to edit your results. • Use as many space/pages in order to have net diagrams, graphs, calculations and conclusions. 3.1 1201 IDEAL MODEL This "ideal model" is about requirement 2.1 Model diagram 3.1.1 Note: Use copy (from Simplorer) and paste to show the complete diagram 3.1.2 Graphs Note: Use copy (from Simplorer) and paste to show the graphs.
