In this paper a switch mode power supply design for electromagnet systems is presented. It is based on a boost converter with power factor correction and a two-switch forward converter. The powered electromagnetic systems in this research are part of various electrical contact apparatus such as electromagnetic contactors, relays, circuit breakers etc. The proposed schematic works in a wide input voltage range which solve the problem with the voltage sag occurring in the energy distribution system. The proposed solution ensures stable operation of the contact equipment and the relay circuits in their industrial application.
