Summary:In this paper is presented power supply circuit designed to deliver desire energy to magnetometers, used for measurements of geomagnetically induced currents (GICs) in a high voltage (HV) networks. The buck-boost dc-dc converter's topology is investigated with software Cadence OrCAD. The input voltage V in is expected to vary between 8 V and 15 V. The presented converter ensures stable dc output voltage V out of 12 V. The power supply circuit is implemented on PCB. Efficiency as function of input voltage is investigated. The maximum achieved efficiency result of the designed circuit is equal to 85.7 %.
