A method and apparatus for controlling AC power from the stator of an alternator in which groups of windings have various numbers of turns and various numbers of poles per winding can be connected in series to achieve optimum power generation at one RPM and in parallel to achieve optimum power generation at another RPM.
A regulation system for a permanent magnet generator for generating electrical power and for supplying the electrical power to a load comprises a switching circuit connected between the permanent magnet generator and the load, the switching circuit being capable of regulating the electrical power being supplied to the load and a control circuit connected to the switching circuit, the control circuit for determining the amount of electrical power being supplied by the permanent magnet generator and for controlling operation of the switching circuit to regulate the electrical power being supplied to the load.
A system and method to dynamically control a switching alternator is disclosed. A switching alternator system is disclosed that includes a plurality of windings configured to deliver an AC power and a plurality of switches configured to switch an electrical configuration of the plurality of windings. A processor is included that is programmed to control the plurality of switches to deliver a desired DC power.
A rotating electrical machine, such as an aircraft starter-generator, that includes an exciter that has its stator windings supplied with electrical power from a power supply. One or more switches are electrically coupled between the exciter stator winding and the power supply and are configured and controlled so that a capacitance may be selectively placed electrically in series with the exciter stator windings.
A rotating electrical machine, such as an aircraft starter-generator, includes an exciter that has its stator windings divided into a number of sections. A plurality of switches are electrically coupled to the exciter stator winding sections and are configured and controlled so that the exciter stator winding sections may be selectively coupled in series or in parallel with one another, and selectively coupled to receive either DC or AC power.
