Abstract :
This report deals with the system compatibility of generators (diesel engine driving an alternator) supplying UPSs and presents an overview of UPS and generator characteristics. Methods are developed for evaluation of harmonic currents and voltages when the UPS input consists of 6- and 12-pulse rectifiers with and without filters. Some numerical examples are compared with test results
