DC/DC Converter Low Harmonic Buck/Boost Converter — 2

The Switch-Mode Power Supplies (SMPS) based on buck/boost converters are
essential for portable electronic devices to enhance their efficiency and increase battery life.
Engineers have classified DC/DC converters into various types such as buck converters,
boost converters, buck/boost converters and CUK converters. Today most portable
electronic devices employ DC/DC converters in one way or another in order to step up or
step down voltages rather than traditional method using voltage regulator.
