Abstract
A variable-speed constant-frequency (VSCF) power converter includes a generator control operable to regulate an output voltage of a variable frequency generator at a variable frequency. The VSCF power generator also includes an inverter control operable to regulate a VSCF output voltage at a point-of-regulation at a constant frequency, where the generator control and the inverter control independently control a main line contactor of the point-of-regulation to provide redundant fault protection for an aircraft use.

A variable-speed constant-frequency (VSCF) power converter, comprising:
- a generator control operable to regulate an output voltage of a variable frequency generator at a variable frequency;
- and
- an inverter control operable to regulate a VSCF output voltage at a point-of-regulation at a constant frequency, wherein the generator control and the inverter control independently control a main line contactor of the point-of-regulation to provide redundant fault protection for an aircraft use.
A variable-speed constant-frequency (VSCF) power generating system comprising:
- a variable frequency generator;
- and
- a VSCF power converter in an aircraft power panel, the VSCF power converter comprising:
- a generator control operable to regulate an output voltage of the variable frequency generator at a variable frequency;
- and
- an inverter control operable to regulate a VSCF output voltage at a point-of-regulation of the aircraft power panel at a constant frequency, wherein the generator control and the inverter control independently control a main line contactor of the point-of-regulation to provide redundant fault protection for an aircraft use.
A method of controlling a variable-speed constant-frequency (VSCF) power converter, the method comprising:
- regulating an output voltage of a variable frequency generator at a variable frequency by a generator control of the VSCF power converter;
- regulating a VSCF power converter output voltage at a point-of-regulation at a constant frequency by an inverter control of the VSCF power converter;
- and
- independently controlling a main line contactor of the point-of-regulation by the generator control and the inverter control to provide redundant fault protection for an aircraft use.
