ABSTRACT
The principle behind Flyback converters is based on the storage of energy in the inductor during the charging, or the “on period”, ton, and the discharge of the energy to the load during the “off period”, toff. There are four basic types that are the most common, energy storage, inductor type converter circuits: step down, or buck converter, step up, or boost converter, inverting, buck-boost converter and isolated, buck-boost converter. The Continuous Mode demands a high current flowing through the switch during turn-on, and can lead to high switch dissipation. The Isolated Buck-Boost Converter can provide line isolation, and also has the capability of multiple outputs, which require only a diode and a capacitor; the filter inductor is built-in. The skin effect on an inductor is the same as a transformer. In the discontinuous, flyback design, the skin effect has to be treated just like a high frequency transformer.
