Power Converters And Methods For Reducing Voltage Changes At An Output Of A Power Converter

摘要

Example switching power converters and methods for reducing voltage changes at an output of a power converter are generally disclosed. According to one aspect, a switching power converter includes an input, an output for providing an output voltage, at least one switch capable of causing a voltage overshoot of the output voltage when the switch is turned on, and a controller. The controller is configured to sense the output voltage, compare the sensed output voltage to a voltage reference, and adjust operation of the power converter based on the comparison of the sensed output voltage and the voltage reference to maintain the output voltage. The controller is further configured to decrease the voltage reference from a normal operation value to an overshoot reduction value before turning on the switch to decrease the output voltage and reduce an overshoot of the output voltage in response to turning on the switch.
