Compact DC-DC converters have made their way into millions of electronic products and systems. The vast majority of these depend upon an AC-DC power supply (metal box or chassis-mount) to convert the AC into a DC voltage from which the converters can operate. In addition, regulations have mandated that these power supplies include Power Factor & Harmonic Correction (PFHC) to maximize the available power from the power grid. Add to this the need to be as small as possible and to operate with in harsh ambient temperatures and the designer is faced with a problem that is not easily solved.
