Abstract

Power supply is an important component of any electronic system. Some sensitive electronic-telecommunication systems that operate at frequencies around the switching frequency of their power supply or its high frequency harmonics are affected by switching noise. The purpose of this paper is to design and implement resonant switching power supply to reduce switching noise. In addition to reducing switching noise, soft switching, which also reduces losses and extends the life of parts, is another specification that is optimal for a power supply. For this purpose, the design process of the resonant switching power supply LLC with soft switching is described. Then the designed power supply is simulated in PSIM software and the design is validated. Finally, the designed converter is constructed and tested in a practical way. The results show that the designed power supply is able to generate Ripple noise less than 200 mV at the output voltage of 24 V, which is a desirable value.
