FIELD: electrical engineering; control of DC motors. SUBSTANCE: two amplifiers are installed between inputs of phase shifting devices and output of control pulse shaper. Amplifiers have forward and reverse polarity transistors 18 and 19, feedback resistors 23 and 24, and output resistors 25 and 26. Resistors 21 and 22 are placed between amplifier input and shift voltage source. EFFECT: enlarged operating capabilities. 5 dwg
