Abstract
Methods, devices, and circuits are disclosed for a buck-type AC/DC converter with DC output harmonic control. One example is directed to a AC/DC converter configured to generate a DC output at a target output voltage. The converter is configured to, responsive to an AC input voltage being less than the target output voltage, convert the AC input voltage to a boosted DC output voltage. The converter is further configured to, responsive to the AC input voltage being greater than the target output voltage, convert a first portion of the AC input voltage to a clamped boosted DC output voltage. The converter is further configured to buffer a second portion of the AC input voltage to a buffered DC voltage. The converter is further configured to apply the buffered DC voltage to the clamped boosted DC output voltage.
