FIELD: electricity.
SUBSTANCE: invention relates to a pulsed technique and can be used in the stabilized secondary power sources, electric machine control systems, devices, measuring technology and automation. This object is achieved by generating the pulse-modulated control signal, which is proportional to the magnitude of the constant component of the feedback current that changes the angle of inclination of the sawtooth voltage across the capacitor. The width of the pulse signal is determined by the duration of the rise ramp until it reaches the reference voltage. The device of forming the double-channel pulse-modulated signal consists of a back connection voltage converter into the current, which is formed on an operational amplifier, a resistor, the MIS transistor, which provide high gain and thermal stability.
EFFECT: invention provides improving in voltage quality and current stabilization by increasing the thermal stability.
