No break power transfer can be accomplished from ground power to an aircraft or between multiple sources on an aircraft with 400-Hz electrical power using a frequency reference autoparallel unit (FRAPU). The no-break function can also be included in the control functions of the feedback control system of the electrical power generating system. The parameters that are controlled to achieve this successful electric power generator system approach to no-break transfer, allowing the airframe manufacturer and operator to take advantage of this normal operating function for commercial and military mission activities are discussed. The following topics are discussed: desirability of no-break power transfer, optimal no-break power transfer, the reason for minimizing circulating watts and VARs, power flow control, other factors affecting circulating power, synchronization control, and means of no-break transfer.
