Abstract
A power converter is configured for usage in a power factor correction system. The power converter comprises a transformer with a primary winding and a secondary winding which isolates a primary side from a secondary side. A primary side switch is coupled to the primary winding. An isolator coupled to the primary side switch isolates the primary side from the secondary side and comprises a signal pathway passing a digital signal from the primary side to the secondary side. Power factor correction circuitry is coupled to the primary side switch and adjusts electric load characteristics to improve power factor toward unity.
