Hybrid electrical power generator and battery charging system

A power generating system comprising an electrical generating set and a modulator configured to maintain optimal voltage regulation under varying load conditions. The system includes a controllable current power source; an active rectifier coupled to the controllable current power source, configured to rectify an output of the controllable current power source to supply utility-grade power or for recharge of a battery or batteries. A controller is configured to adjust at least one of the parameters of the controllable current power source and/or supply from the generator and a parameter of the active rectifier in response to a target output.
