Abstract
A method and system for operating a hybrid propulsion system, includes controllably providing a first power to a first bus and a first inverter, electrically coupling a first motor with a second inverter by way of a second bus, operably converting, by the second inverter, the first power received by the first inverter to a starting power adapted for starting the first motor, and increasing, by the second inverter, the starting power to match the first power received.
Claims16
A method of operating a hybrid propulsion system, the method comprising:
- controllably providing a first alternating current (AC) power to a first bus and a first inverter;
- electrically coupling a first motor with a second inverter by way of a second bus;
- operably converting, by the second inverter, the first AC power received by the first inverter to a starting AC power adapted for starting the first motor;
- increasing, by the second inverter, a frequency of the starting AC power to match a frequency of the first AC power received;
- and
- electrically coupling the first motor with a first bus when the starting AC power matches the first AC power received.

A hybrid propulsion system, comprising:
- a first inverter;
- a second inverter electrically coupled with the first inverter and selectively couplable with either a first bus or a second bus;
- a first motor selectively couplable with either the first bus or the second bus;
- and
- a controller configured to:
- electrically couple the first motor with the second inverter by way of the second bus;
- operably convert, by controlling the second inverter, a first power received from the first inverter to a starting alternating current (AC) power adapted for starting the first motor;
- increase, by controlling the second inverter, a frequency of the starting AC power to match a frequency of the first bus;
- and
- electrically coupling the first motor with a first bus when the starting AC power matches the frequency of the first bus.
