  • Feedback control loop in a power supply circuit
    Patent number: 5581450
    Abstract: A feedback loop in a power supply operating in a switched mode has a dual response controller which provides slow response to superimposed ripple on the power supply output by two impedances in series, and when there is transient deviation on the output diode, switching brings in a further impedance in parallel with one of the two impedences to reduce the overall impedence and provide a faster response for the control of the switching mode.
