A hybrid induction machine includes a stator with an input winding, a plurality of output windings with output ports, and a rotor connected to a flywheel operating as a reserve of kinetic energy to buffer surges in demand for electrical power due to large, pulsed loads with high repetition rates. Degradation of power quality at the output ports of the hybrid induction machine due to electrical noise on a main bus providing electrical power to the hybrid induction machine and other apparatus can be eliminated through the use of feed-forward harmonic cancellation signals, galvanic and magnetic isolation of the output ports, and damper networks.

Like a transformer that can increase or decrease AC voltage or current by increasing or decreasing the turns-ratio of the transformer an amplification factor is developed. And like a transistor that can amplify/attenuate an electrical signal and by manipulating the hfe of the transistor, it could increase or decrease the amplification factor of the transistor. Likewise, the MAM unit, depending on the number of phases used, can amplify the power for a given output motor by increasing the number of phases of the output AC motor, which substantially reduces the amount of current an AC motor will draw for a specific amount of torque. By increasing the number of phases on an AC synchronous, asynchronous, axial, induction, or reluctance type motor, using alternating current, you can increase the efficiency, which implies an amplification factor of the motor thereby reducing the applied current required for a given amount of torque/speed.

A method, which is executed by a controller, for controlling a power supply circuit of an electric motor, the power supply circuit comprising an inverter supplying the motor with power via a power supply link, the method comprising detecting an increase in the voltage across the terminals of the power supply link while overcoming the inductive component of the impedance of the power supply link, and inhibiting an output for controlling the inverter if the increase in voltage exceeds a predetermined value for a predetermined duration. Also a controller for a power supply circuit that is configured to execute the method, an electrical power supply system for a motor and an aircraft comprising such a system and a control method.
