Abstract
An electric power conversion system has an adaptable transformer turns ratio for improved efficiency. The transformer has multiple taps on its primary. Switching circuitry is configured to connect an energy source to the taps in at least two modes such that the transformer operates with a first primary-to-secondary turns ratio in the first mode and with a second primary-to-secondary turns ratio in the second mode. The first turns ratio is greater than the second turns ratio. Control circuitry is configured to operate the switching circuitry in the first mode when a voltage level of the energy source is above a first threshold and to operate the switching circuitry in the second mode when the voltage level is below a second threshold.
