In a phase-controlled converter supplying dc load, the maximum displacement factor is unity for maximum dc output voltage. However, in the case of the cycloconverter, the maximum input displacement factor is 0.843 with unity power factor load [8,15]. The displacement factor decreases with ...
5. Connect 15V DC power supply to [M6]-JP1 and ensure that [M6]-SW1 is in the "Off" position. 6. Connect banana cable from [Main]-BS1 to [Main]-BS3 (This will connect the rectifier output to the boost converter input). 7. Connect banana cable from [Main]-BS4 and [Main]-...
For a conventional three-phase bridge rectifier feeding a capacitive filter, these two characteristics provide maximum throughput power with negligible ill effects.; In order to obtain low-distortion input current at unity power factor, this thesis will utilize Pulse-Width Modulation (PWM) techniques ...
