摘要：

This contribution presents a mathematical tool for analytical calculation of the optimum switching frequency and transformer parameters of a switching power supply utilizing a two-switch forward converter. The calculations are based on minimization of total power loss of the converter with given switching semiconductors and size of transformer and inductor core. This allows the designer to construct a converter with greatest efficiency using given parts (keeping cost of the components). The results are power saving, less waste heat and possibly smaller size and weight of the converter or power supply. Applications include photovoltaic inverter, electric vehicle charging, industrial power supply and any isolated DC/DC converter in general.
