  • Switch mode power supply (SMPS) circuit
    Patent number: 11817787
    Abstract: One example discloses a switch mode power supply (SMPS) circuit configured to receive an input voltage and generate an output voltage, including: a set of switching devices configured to receive the input voltage; a first transformer, having an input winding coupled to the switching devices, and an output winding configured to generate the output voltage; a second transformer, having an input winding coupled to receive the output voltage from the first transformer, and an output winding configured to generate an output voltage monitoring signal; and a controller configured to control the switching devices based on the output voltage monitoring signal.

  • Power supply arrangement comprising a DC/DC converter with primary-side control loop
    Patent number: 6625042
    Abstract: A power supply arrangement having a DC/DC converter is presented that includes a control loop on the primary side of the isolation transformer within the DC/DC converter to control the voltage on the primary winding. The energy transfer across the isolation transformer is effected via control switches that alternately charge and discharge a capacitor through the primary winding. The control loop preferably adjusts the duty cycle of these control switches to control the voltage on the primary winding.
