Abstract
Power supplies and related methods capable of reducing output voltage ripple. A power supply provides an output voltage to a load and controls the output voltage to approach a target voltage. The output voltage is compared with the target voltage to generate a control signal, which controls an output current of the power supply. When the control signal causes an increase in the output current, the target voltage is reduced.
Claims8
A method of reducing ripple for use in a power supply, the power supply providing an output voltage to a load, and causing the output voltage to approach a target voltage, the method comprising:
- comparing the output voltage and the target voltage to generate a control signal;
- and
- changing the target voltage according to the control signal;
- wherein the target voltage is lowered when the control signal indicates that output current increases.
A power supply, the power supply providing an output voltage to a load, and causing the output voltage to approach a target voltage, the power supply comprising:
