Abstract
A method and system for transferring a load from a first AC voltage source to a second AC voltage source. A temporary voltage source is connected to the load and to the first voltage source via a resistor. The first voltage source is disconnected from the load. The second voltage source is connected to the load. Finally, the temporary voltage source is disconnected from the load. The temporary voltage source may be independent of the first and second voltage sources, or may obtain voltage from the first or second voltage sources. The connecting and disconnecting is done by mechanical switches, by thyristors, or by mechanical switches and thyristors in parallel or in series.
