Abstract: An electrical propulsion system includes an electrical motor configured to drive one or more propellers of the aircraft, a capacitor configured to stabilize a direct current (DC) bus voltage, a first inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to alternate current (AC) voltages to drive a first set of stator windings of the electrical motor, in response to a first pulse width modulation (PWM) vector, and a second inverter circuit coupled to the capacitor and configured to convert the DC bus voltage to AC voltages to drive a second set of stator windings of the electrical motor, in response to a second PWM vector. The first PWM vector and the second PWM vector are substantially equal and opposite vectors.

Abstract: The embodiments of the present disclosure provide systems and methods of forming a transformer with enhanced leakage inductance for power conversion. The transformer may include a toroidal core, a primary winding around a first portion of the toroidal core, a secondary winding around a second portion of the toroidal core different from the first portion, and a magnetic material disposed within a cavity formed by the toroidal core. The magnetic material may comprise a ferrite. The method of forming a transformer may include the steps of providing a toroidal core, winding a primary coil around a first portion of the toroidal core, winding a secondary coil around a second portion of the toroidal core, and disposing a magnetic material within the cavity formed by the toroidal core to enhance the leakage inductance of the transformer.

Abstract: An aircraft system for damping movement of a structural flight element. The aircraft system including a moveable aircraft structure, a power source, a controller, a resistor, and a first transistor connected in series to the resistor. When the power source of the aircraft is providing power, the controller controls the first transistor to prevent current flow through its terminals and through the resistor. Further, when the power source of the aircraft is not providing power, the first transistor allows current generated by a back EMF (electromotive force) voltage to flow through its terminals and through the resistor, the back EMF voltage being created by movement of the moveable aircraft structure.
