Abstract
A power generation system includes a generator configured to output alternating current (AC) power, an active rectifier configured to receive the AC power from the generator, convert the AC power to direct current (DC) power, and output the DC power. A current injector is connected to the active rectifier and is configured to provide an injection current to power flowing through the active rectifier. The injection current includes a reactive component.
Claims20
A power generation system comprising:
- a generator configured to output alternating current (AC) power;
- an active rectifier configured to receive the AC power from the generator, convert the AC power to direct current (DC) power, and output the DC power;
- and
- a current injector connected to the active rectifier and configured to provide an injection current to power flowing through the active rectifier, the injection current including a reactive component.
A method for reducing a modulation index in a DC link voltage of an active rectifier, the method comprising:
- injecting an injection current into current flowing through the active rectifier using a current injection circuit, wherein the injection current includes a real component and a reactive component.
An aircraft electrical system comprising:
- at least one generator disposed within a gas turbine engine generator;
- a power distribution system electrically connected to the at least one generator, the power distribution system including at least an active rectifier and a current injection circuit, the current injection circuit being configured to provide an injection current to the active rectifier, wherein the injection current includes a reactive component;
- and
- a plurality of electrical systems disposed throughout the aircraft and being configured to receive power from the power distribution system.
