HACKAREKRETS FOR INKOPPLING MELLANEN LIKSPENNINGSKELLA OCH EN BELASTNING |
摘要 |
A force commutated thyristor chopper is disclosed in which a single commutation inductor is coupled in the free-wheeling path of the chopper together with a free-wheeling diode. The single inductor provides a chopper of relatively simple configuration in which main and commutator thyristors couple a commutation capacitor to opposite ends of the commutation inductor, and a charging diode is coupled in parallel with the commutator thyristor to facilitate charging of the commutation capacitor in opposite senses. The resulting circuit arrangement operates in a highly effective and efficient manner, minimizes trapped energy and protects the various component parts thereof by preventing dangerously high current and voltage transients. |
