摘要： A circuit arrangement has an even number of semiconductor switches, which are connected in series and contain in each case two load terminals and a control terminal and are associated with one another in pairs. The circuit arrangement also contains, for each semiconductor switch, a driver for actuating the semiconductor switch via the control terminal thereof and, for every two semiconductor switches that form a switch pair, contains a switching power supply which is supplied with energy from an electrical voltage between the two load terminals of a first semiconductor switch of the switch pair and supplies both the driver of the first semiconductor switch and the driver of the second semiconductor switch of the switch pair with energy.

摘要： A circuit arrangement includes two switching group series circuits of switch assemblies, switch-mode power supply units, and two capacitor bridges connecting the switching group series circuits. Each switch assembly has a parallel circuit of a semiconductor switch and a freewheeling diode as well as a driver for actuating the semiconductor switch. Each switch-mode power supply unit is associated with a switch pair of semiconductor switches and supplies the drivers of both semiconductor switches of the switch pair with energy. Each switch pair is formed by a semiconductor switch of a first switching group series circuit and a semiconductor switch of a second switching group series circuit. A power convertor module having the circuit arrangement is also provided.
