A power generation and distribution system utilizes two or more AC generators each of which may be driven by a separate prime mover such as a turbine. The generators may be driven at different rotational speeds. AC power from the generators may be rectified and applied to a common DC bus. Electrical

A power generation and distribution system utilizes two or more AC generators each of which may be driven by a separate prime mover such as a turbine. The generators may be driven at different rotational speeds. AC power from the generators may be rectified and applied to a common DC bus. Electrical loads may be applied to the common bus and may establish an electrical power requirement. Allocation of electrical power requirement may be made among the generators based on power available from the turbines.

We claim: 1. Apparatus for generating and distributing electrical power on an aircraft comprising:a first AC generator driven by a first engine of the aircraft at a first rotational speed, the first AC generator delivering power directly to a common DC bus via a first rectifier;a second AC generator

We claim: 1. Apparatus for generating and distributing electrical power on an aircraft comprising:a first AC generator driven by a first engine of the aircraft at a first rotational speed, the first AC generator delivering power directly to a common DC bus via a first rectifier;a second AC generator driven by the first engine or a second engine of the aircraft at a second rotational speed different from the first speed, the second AC generator delivering power directly to the common DC bus via a second rectifier;the common DC bus for supplying electrical power from either of the generators to an electrical load connected to the common DC bus without paralleling AC power from the first AC generator and the second AC generator; anda supervisory controller configured to provide signaling to generator control units (GCU) to vary duty-cycles of the first and second AC generators to allocate portions of the electrical load among the first and the second AC generators while the first and second AC generators and the electrical load remain connected to the common DC bus, andwherein generator power share is determined by the supervisory controller responsively to power available from the engines.
