Electrical Power And Computer Control Department Course Title: Power Electronics (2) Course Code: EE423 Prof. Dr. Hamdy Ashour Eng. Mona Ibrahim Sheet(3) Cycloconverters 1) The input voltage to the cycloconverter is 120V (rms). 60Hz. The load resistance is 5Ω and the load inductance is L=40mH . The frequency of the output voltage is 20Hz. If the converters are operated as semiconverters such that 0≤α≤π and the delay angle is αp = 2π/3 , Determine : a) The rms value of output voltage Vo b) The rms current of each thyristor IR c) The input power factor PF 2) The input voltage to the cycloconverter is 120V (rms). 60Hz. The load resistance is 2.5Ω and the load inductance is L=40mH . The frequency of the output voltage is 20Hz. the delay angle is αp= 2π/3 , Determine : a) The rms output voltage Vo b) The rms current of each thyristor IR c) The input power factor PF 3) A single phase resistive load (100Ω) is supplied from a 200V rms, 50Hz supply through a single cyclo-converter. The output frequency equals 10Hz. Sketch the circuit diagram, the input and output voltages , the input and output current, the current and voltage of one thysistor, the control signals of the thyristors.
