Abstract: In this paper described the switching power supply (SPS) unit and represented its importance for electronic circuits in electronic devices. SPS directly affect the operation of electrical circuits and electronic equipment. In particular, this paper describes its use in a portable proton-magnetic resonance (PMR) relaxometer. Especial attention is to the method of constructing the circuit, and also deals with the comparense of the SPS with a transformer power source. This article presents the structure of schematic diagram of the SPS. The SPS structure works without a transformer, which reduces the size of the system and increases overall efficiency. The proposed circuit structure is based on a push-pull controller, a high- frequency converter with an amplifier and a voltage multiplier circuit and a voltage stabilizer. The simulation and experiments confirm the proposed configuration of SPS.
