摘要：A method and system for transferring a load from a first AC voltage source to asecond AC voltage source. A temporary voltage source is connected to the load and tothe 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 voltagesource 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 firstor second voltage sources. The connecting and disconnecting is done by mechanicalswitches, by thyristors, or by mechanical switches and thyristors in parallel or in series.
