Abstract:
1. A method of producing power with controlled frequency from a variable frequency power source comprising the steps of: connecting an AC bus to the variable frequency power source; connecting a multiphase transformer between the variable frequency power source and the AC bus, inputting variable frequency power having a first number of phases to the multiphase transformer and outputting to the AC bus variable frequency power having more than said first number of phases; and connecting to the AC bus a plurality of circuits each having: a rectifier having an input electrically connected to the AC bus and having an output; an inverter having an input electrically connected to the rectifier output and having an output; a load connected to the output of the inverter; and an AC contactor connected between the rectifier and the AC bus, and providing current from the AC bus to each of the plurality of circuits.
