FIELD: electrical engineering, electroactuators. SUBSTANCE: feeding arrangement has alternative current generator with frequency control and high frequency transformer. One end of transformer high voltage winding is connected to power consumer one terminal but second end of high voltage winding is insulated. Powered terminal can be connected by matching device using, for example rectifier or transformer-converter. Low voltage winding of high frequency transformer is connected to alternative current generator which operation frequency changes until resonant oscillations appears. It is optimal operating regime. EFFECT: lower ohmic losses in power line. 2 cl 3 dwg |
