Abstract
The processes of switching from an AC (50/60 Hz) main power-supply system to a standlby system in the presence of different initial phases and a certain delay in switching are considered under the following loads: an asynchronous motor and a power transformer. A new device and algorithm for switching without time delay and, consequently, without load voltage surges are proposed. Switching of power-supply systems using the proposed device and the influence of the switching time on the capacity of the energy-storage unit of the device are considered. The potentialities of a multifunctional device for connecting a standby power-supply system are described.
