TOPOLOGIES AND METHODS FOR TURBINE ENGINE START INVERTERS |
| 摘要 |
A start inverter for an electric engine start scheme includes an inverter phase leg with solid-state switches and a pulse width modulator operatively connected to the solid-state switches of the inverter phase leg. The pulse width modulator provides command signals to the solid-state switches of the inverter phase leg to invert direct current into alternating current with less ripple than a start inverter with two solid-state switches per phase leg. |

1. A start inverter for a gas turbine engine, comprising:
a plurality of phase legs each having at least three solid-state switches; and a pulse width modulator operatively connected to the inverter phase legs, wherein the pulse width modulator is configured to provide command signals to the solid-state switches that cause the inverter phase legs to invert direct current (DC) power into alternating current (AC) power with less ripple than a start inverter with two solid-state switches per phase leg. |
