Abstract

Systems and methods for the coupling of power through an isolation transformer. The systems generally include a primary side electrically connectable to the primary winding of an isolation transformer, a secondary side electrically connectable to the secondary winding of the isolation transformer, a primary side switch sending power pulses to the secondary side, and a secondary side feedback circuit sending a feedback signal to the primary side. A pulse detector sends power pulses to the secondary side in response to the feedback signal, while a watchdog timer sends a power pulse to the secondary side if a feedback signal is not detected within a predetermined period of time. Secondary side circuits including a slow-start circuit and a wake circuit portion manage initialization and low-load operating power requirements, respectively.
