Abstract
A high voltage direct current (DC) power supply applies an alternating current (AC) concept of power factor correction (PFC) to supply DC voltage using a series PFC boost converter. Multiple series DC/DC boost converters are controlled using voltage feedback from the filtered voltage input in each PFC boost stage to stabilize the DC input voltage and achieve a large step-up voltage ratio. Input voltage feedback is utilized by the controllers in all boost stages of the PFC boost converter so as to appear resistive and compensate for the DC source impedance, which significantly reduces the amount of damping capacitance needed by the system.
