IMPLEMENTATION OF COMPACT SWITCHING POWER SUPPLY WITH HIGH POWER

In this paper we will present a power supply – three phase AC/DC converter – with special requirements for power factor and dimensions. Development of such compact devices – up to 8cm3 – provides possibility for mass production of electronic subsystems intended to be implemented within the low voltage grid, reducing emission of higher harmonics (up to 40th) in the power grid and achieving maximal efficiency. Indirectly, this concept enables control of electric energy consumption of small loads. Development of power supply following these characteristics is significant for all producers of electronic equipment compatible with IEC-1000-3 standard
