Abstract
An information handling system (IHS) is provided which includes an inverter circuit capable of operating over an extended DC input voltage range without substantial degradation in efficiency. A DC input voltage is converted to an AC input voltage. A first turns ratio of an AC transformer is applied to the AC input voltage if the DC input voltage is within a first voltage range. A second turns ratio of an AC transformer is applied to the AC input voltage if the DC voltage is within a second voltage range.
