  • Mode operation detection for control of a power converter with an active clamp switch
    Patent number: 11888405
    Abstract: A primary controller comprising a control circuit coupled to determine a mode of operation and to generate a first mode of operation signal and a second mode of operation signal. The control circuit coupled to generate a control signal in response to the first mode of operation signal or the second mode of operation signal, the control signal causes a delay time to enable a turn ON of a power switch after a turn OFF of a clamp switch. The control circuit coupled to output a clamp drive signal to control the clamp switch and comprises a delay circuit coupled to receive the first mode of operation signal and the second mode of operation signal, wherein the delay circuit is coupled to apply a first delay time or a second delay time to the control signal, the second delay time being longer than the first delay time.

  • Mode operation detection for control of a power converter with an active clamp switch
    Patent number: 11632054
    Abstract: A primary controller configured for use in a power converter comprising a control circuit configured to determine a mode of operation of the power converter in response to a drive signal of a power switch. The control circuit further configured to generate a control signal in response to a signal representative of the mode of operation of the power converter, wherein the control signal represents a delay time to enable a turn on of the power switch after a turn off of a clamp switch. The control circuit further configured to generate a clamp drive signal to control the clamp switch. The primary controller further comprises a drive circuit configured to generate a drive signal to enable the power switch to transfer energy from an input of the power converter to an output of the power converter.
