FIELD: electricity.SUBSTANCE: device exchanges electric energy between power systems (1) and (2). Voltage inverters at each side are formed by diode bridges (7) and (8) and bridges (11, 12) of back-to-back closing gates. The controlled bridges (11) or (12) can be switched off for the periods of unidirectional energy transmission to perform routine maintenance or to reduce losses of electric energy.EFFECT: improvement of reliability, carrying capacity and increase of efficiency factor.2 cl, 1 dwg |
