DC-DC Converter Universal Block

This is the ideal Simulink block of DC-DC converters; where users can simulate Simulink model of basic DC-DC converters. Users can choose between three types of DC-DC converters: buck, boost, and buck-boost; choose between three modelling methods: mathematical, state-space, and circuitry; choose between types of semiconductors: MOSFET and IGBT; editing the required parameters; apply to the Simulink application for simulation, as well as presenting the industrial uses.
