The the prospect of construction a constant-current voltage raising converter, not requiring the use of a transformer, is considered. The given circuit can be used as the power supply for an adjustable electric drive, on the basis of a transistor converter, and included in independent electric supply systems. The expressions for circuit parameters in a quasistatic mode, and also synthesis techniques for a two-planimetric regulation system with PWM, providing low dc-voltage sensitivity in parameters and loading current are given, along with a formal mathematical model of the system designated "the power supply - electrical drive".
