METHOD AND SYSTEMS FOR AN ENGINE STARTER/GENERATOR |
摘要 |
A method and system for an engine starter/generator is provided The starter/generator system includes a three phase squirrel cage induction machine, a three phase inverter/converter electrically coupled Io the three phase squirrel cage induction machine The starter/generator system also includes a bidirectional DC-DC converter electrically coupled to the three phase inverter/converter, and a digital control board configured to sensorlessly determine a rotor angle from a plurality of phase currents to the induction machine during a start mode. During the start mode, logic in the digital control board configures the starter: generator system into a combination of an induction motor, a three phase DC-AC inverter, and a DC -DC boost converter, and during a generate mode, the logic in the digital control board configures the starter generator system into a combination of an induction generator, a three phase AC-DC converter, and a DC-DC buck converter. |
