The calculations of their electric and power regimes were carried out, models of charging units of two types were developed and implemented, their thermal characteristics were investigated. As a result of works execution, the scheme of device's charging circuit was proposed and inestigated. This scheme allows to abandon the use of step-up transformer in a device above ground, increase the frequency of power transfer from surface to submersible part up to 4000 Hz, and, correspondingly, to miniaturize the high-voltage transformer's submersible part, to increase the coefficient of efficiency of device charging circuit in comparison with operational schemes due to the application of inductive current-limiting. Thermal characteristics of charging units of two types were defined: the first typeis with frequency converter (FC) situated in the surface part and another one is with FC situated in the submersible part of the installation. The received results will be used at the development of compact PCG of new generation with the improved mass-overall and field-performance data, designed for the treatment of oil wells.
