Abstract

The device is electrical and is used to control a variable-voltage-to-constant voltage converter. The purpose of the invention is to expand the functionality. When a constant voltage is applied to the stator winding 2 of the selsyn (s) 1, the phase windings 3 are relieved of the voltage to control the transformer. The determined phase of the control signals is set by turning it to the appropriate position of the rotor C 1. When high IS g SL tsd Od from the sl fftaeffw ItHotu / itt

Description

1234935 A single phase wiring diagram is simplified (, 5) and three additional JS-circuits, since resistor A and capacitor 5 of the Rc circuit are connected in series only between two phase windings. Introduction of the third KS chain

This invention relates to electrical engineering and is intended to d: controlling a variable-to-constant voltage converter.

The purpose of the invention is to expand the functionality.

The drawing shows the scheme predpagaye of the 1st device.

The device contains a selsyn 1, the stator winding 2 of which is connected to the network (is-in), and the ends of the 3 phase windings are connected via KC-chains on resistors 4 to capacitors 5. Kjiet iMb, which are connected to the control electrodes of the thyristors, are connected through additional R C - chains on resistors 6 and capacitors 7 to decoupling elements 8.

The device works as follows.

When a constant voltage is applied to the stator winding 2 of Sean 1 from its phase windings through the isolating elements 8, resistors 6 and capacitors 7, they remove control signals from the converter, the specific phase of which is set by turning the corresponding angular position of the selsyn rotor 1. One phase is simplified; so: as a resistor 4 and a capacitor 5 in series
