ABSTRACT:
A transfer compensation circuit for use in a standby A-C power system which compensates for the transient in system output voltage which occurs when the system transfers from the conventional A-C input voltage to the standby power system. The compensation is dependent on the total load on the system at the instant of transfer. The total load includes both the external load connected to the system load and the battery in the standby supply if the system normally functions to provide charging current to that battery.
