Abstract
A GPU output from a ground power unit (GPU) can be converted to power suitable for starting a jet engine of an aircraft by an auto-transformer rectifier unit (ATRU) of the aircraft. Multiple ATRUs, each connected to a corresponding GPU, may output multiple ATRU outputs, and combining these multiple ATRU outputs can generate a combined power, which can satisfy the power requirements for starting a jet engine when they exceed what can be supplied by a single GPU. The combining is possible when the outputs of the ATRUs are synchronized, which can require generating and sharing a sync signal between the ATRUs that is synchronous with an ATRU designated as the master (i.e., reference) for the other ATRUs.
