The phase shift full-bridge DC-DC converter is an H-bridge consisting of four switches, in which the power transferred to the load is controlled by creating a phase difference between the switching times of the opposite switches in the two legs. Also, by using parasitic elements of the circuit, including the dispersion inductor of the transformer and the leakage capacitor of the keys, and creating a suitable dead time between the turning off of a key in one leg and the turning on of another key in the same leg, switching is done at a voltage close to zero, and losses are greatly reduced. In this way, this converter has the ability of soft switching like the resonant converter, while it does not have the disadvantages of the resonant converter such as variable frequency. This converter is very popular in industrial applications due to low electromagnetic interference, simplicity of structure, switching at zero voltage, etc. Today, this converter is perhaps the most suitable option for electric car battery chargers. In order to apply pulse to the keys of this converter, usually 3895 or 28950 integrated circuit is used. These integrated circuits control the circuit in an analog way. In this thesis, the control of this converter is done digitally using ATmega328 microcontroller. Controlling the full-bridge phase shift converter using a microcontroller will make any necessary changes in the control circuit possible only by changing the software.
