  • Publication number: 20180083542
    Abstract: A controller for use in a two-stage power supply is coupled to control switching of a switching element to regulate a transfer of energy from an input to an output of a flyback converter. The controller activates a boost switching element during a first interval in each line half cycle of an input voltage to boost an output voltage at an output of a boost-bypass converter. The controller deactivates the boost switching element during a second interval in each line half cycle such that the output voltage of the boost-bypass converter drops towards the input voltage during the second interval while the output voltage of the boost-bypass converter is greater than the input voltage. The controller controls the output voltage to follow the input voltage during a third interval of each line half cycle while the boost switching element remains deactivated and the input and output voltages are substantially equal.

    Abstract: A switched mode power converter (SMPC) has an isolation transformer for power transfer and a communication circuit for data communication between the primary side and the secondary side. The SMPC includes a primary switch controller configured to transfer power from a primary side to a secondary side by controlling a primary switch ON for an ON time period and then controlling the primary switch OFF for an OFF time period. The primary switch controller controls the ON time period of the subsequent power transfer cycle to start a time delay after the end of the OFF time period of the previous power transfer cycle. The communication circuit comprises a magnetically coupled transmission winding and reception winding, a communication switch, and a communication controller to control the communication switch to allow charge flow through the transmission winding during at least part of the time delay for data communication.
