FIELD: electricity. ^ SUBSTANCE: high-voltage DC stabiliser, comprising a stabilising element, a voltage converter, connected to the stabilising element and to the primary transformer winding, the secondary winding of which is connected to a double-channel valve-capacitor unit. A voltage divider connected to the switch via a middle point is connected to the positive terminal of the valve-capacitor unit. An inversion unit 11 connected to the switch is connected to the negative terminal of the valve-capacitor unit. Therefore, with the help of the switch, voltage polarity is selected, for which stabilisation is carried out. The switch is connected with the metre of the feedback signal. An auxiliary rectifier is connected to the additional winding of the transformer and joined to the feedback signal metre. ^ EFFECT: possibility to produce stabilised voltage of positive or negative polarity, which makes it possible to supply to high-voltage devices with supply of various polarity, and provides a low potential at metering and control circuits no matter what the voltage polarity at the outlet is. ^ 2 dwg |
