Abstract
A power conversion apparatus with oscillation reduction control supplies power to a load through an output end. The power conversion apparatus includes a transformer, a power switch, a control module, and an oscillation reduction control module. A primary side of the transformer receives an input voltage, and a secondary side of the transformer is coupled to the output end. The power switch is coupled to the primary side. The control module is coupled to the power switch, controls the power switch continuously turning on and turning off, and converts the input voltage into an output voltage. When the oscillation reduction control module detects a resonance voltage through the secondary side, the oscillation reduction control module performs an oscillation reduction operation to the resonance voltage to reduce an amplitude of the resonance voltage by a damper.
