Single phase input hybrid rectification method employing auxiliary rectification
 A single phase AC input voltage is subjected to a single-phase full-bridge rectifier to obtain a first rectified voltage. The first rectified voltage has a fundamental DC component and a harmonic component, the harmonic component being defined by a ripple voltage of the first rectified voltage. The first rectified voltage is then subjected to an auxiliary rectification in which the ripple voltage of the first rectified voltage is rectified. A resultant auxiliary DC component is added to the fundamental DC component to obtain a DC component of a rectified output voltage.
