reduction of systemeigenschwingungen in a converter with spannungszwischenkreis operated electric zwischenkreises of network and korrespondierender spannungszwischenkreis - umricguardians
Two IGBT transistors (T7) for a positive intermediate circuit bus bar and (T8) for a negative intermediate circuit bus bar operate alongside mains power input chokes (LK1-LK3) as switches for disconnecting an intermediate circuit. Each transistor has a recovery diode (D7,D8). These diodes are connected in anti-parallel. A voltage intermediate circuit is balanced by means of Y-capacitors (CY1,CY2). Independent claims are also included for an electric drive mechanism with an intermediate circuit voltage converter and for an intermediate circuit voltage converter.
