摘要： 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.

摘要： A switching power supply includes power factor correction circuitry and a standby output converter. One or more loads may be coupled to one or more outputs of the switching power supply. The switching power supply is configured to disable the power factor correction circuitry under some load conditions and to enable the power factor correction circuitry under other load conditions. As a consequence, power that would have been drawn by the power factor correction circuitry is conserved when the power factor correction circuitry is disabled.
