Abstract:
1. Voltage regenerator (VT) including at least a first regenerator stage (VT I ) and a second regenerator stage (VT II ), each said regenerator stage having an input connection, with a first input subvoltage (U EI ) and a second input subvoltage (U EII ), respectively, attached at each input connection, and which added together form an input voltage U E , said first and second regenerator stages having first and second output connections, respectively, whereby at the first output connection of the first regenerator stage, with reference to a common potential (P), there is a positive output subvoltage (U AI ), and at the second output connection of the second regenerator stage, with reference to the common potential (P), there is a negative output subvoltage (U AII ), the output subvoltages (U AI ) and (U AII ) added together producing said output voltage (U A ), the first and second regenerator stages, at the input sides, being connected to a DC or AC high voltage net of a board system power supply, said high voltage net having a transient voltages (U the first and second regenerator stages, at the output sides, providing a ruled intermediate circuit voltage of about 600 V–750 V DC or 1000 V AC for supplying an electronic system, the first regenerator stage comprising a first shunt branch with a first inductance coil (L the second regenerator stage (VT
