Abstract
A high voltage DC electric power generating system includes a poly-phase permanent magnet generator having at least one control winding and a plurality of power windings. Each of the power windings is a phase of the poly-phase permanent magnet generator. A passive rectifier connects a switch to an input of each of the power windings such that the switch is a neutral node in a closed state and a disconnect in an open state.
Claims21
A high voltage DC electric power generating system comprising:
- a poly-phase permanent magnet generator having at least one control winding and a plurality of power windings, each of said power windings being a phase of the poly-phase permanent magnet generator;
- and
- a passive rectifier connecting a switch to an input of each of said power windings such that said switch is a neutral node in a closed state and a disconnect in an open state.
A method for protecting a power generating system comprising:
- detecting a short circuit event;
- selectively removing a neutral node from a poly-phase permanent magnet generator, thereby preventing power generation for a duration of the short circuit event.
A method for balancing a power output of a permanent magnet generator comprising:
- independently controlling a plurality of control windings, each of said control windings corresponding to a single phase of a poly-phase permanent magnet generator.
