  • Power converter controller with stability compensation
    Patent number: 9780666
    Abstract: A switch mode power converter includes a primary side, an energy transfer element, and a secondary side. The secondary side includes output terminals coupled to a load and an output capacitance across the output terminals. The secondary side further includes a compensation signal generator—configured to generate a compensation signal. The compensation signal compensates charging the output capacitance with power transferred from the primary side to the secondary side. The secondary side further includes computational circuitry configured to output an adjusted compensation signal that compensates, based on the compensation signal, one of an output sense signal representative of an output signal at the output terminals and a reference signal representative of a desired output voltage of the switch mode power converter. The secondary side further includes a comparator to compare the adjusted compensation signal with the other one of the output sense signal and the reference signal.
