Independent speed variable frequency based electrified propulsion system architecture

Abstract:

An alternating current (AC) power distribution system may include an independent speed variable frequency (ISVF) generator configured to generate an AC power signal having a frequency that is independent from a frequency of a prime mover. The system may also include at least one AC load configured to receive the AC power signal without performing a full-distribution-power-rated power conversion. In another embodiment, an AC power distribution system includes a generator configured to generate an AC power signal and an AC motor configured to receive the AC power signal without performing a full-distribution-power-rated power conversion, where the AC motor is configured to rotate at a rotational frequency that is independent from a frequency of the AC power signal.
