FIELD: electricity. ^ SUBSTANCE: power converter system (12) is proposed to supply output voltage. System of power supply is arranged with the possibility to operate both in regular and emergency mode. System comprises multiple bridges (14, Ç19, 90) and multiple transformers (20Ç25). System additionally comprises multiple capacitors (32Ç37) of DC, every of which is connected parallel to appropriate bridge. System also comprises controller (11) arranged with the possibility of switching during regular mode of each bridge with appropriate common phase shift. In process of emergency mode controller is arranged with the possibility to switch each of remaining bridges with appropriate specified phase shift in order to generate output voltage. In process of emergency mode at least one of multiple bridges is shunted. ^ EFFECT: invention preserves high quality of output voltage as one system component breaks down. ^ 16 cl, 5 dwg |
