CONTROL SYSTEM FOR SYNCHRONOUS CAPACITOR SWITCH

摘要

Systems and methods for connecting a power source to switched capacitors are provided. A method may be used in controlling the connection of a multiple phase power source to a plurality of capacitors. Each phase of the multiple phase power source is electrically connectable to at least one of the plurality of capacitors through a switching device. The method comprises, for each phase of the multiple phase power source, determining a first voltage of a power signal for the respective phase of the power source using a first voltage divider that is electrically connected to a first terminal of the switching device for the phase. The method further comprises, for each phase, determining a second voltage across a capacitor that is electrically connected to a second terminal of the switching device for the phase. The second voltage is determined using a second voltage divider that is electrically connected to the second terminal of the switching device for the phase. The method further comprises, for each phase, generating a close signal configured to cause the switching device for the phase to close and electrically connect the respective phase of the power source to the capacitor when the difference between the first voltage and the second voltage is approximately zero.
