Zusammenfassung:The converter has a bus capacitor (Cbus) connected between a positive line (10) and a negative line (11) of a power supply bus. Switching legs are connected between the positive line and the negative line of the power supply bus. A switch (I1) is connected to the positive line or negative line of the power supply bus, upstream of the bus capacitor. Another switch (I2) is connected in series with the former switch on the positive line or negative line of the power supply bus, downstream of the bus capacitor. A control unit (3) controls the switches. Junction FET transistors of the switching legs are fabricated from silicon carbide or gallium nitride. An independent claim is also included for a variable speed drive comprising a rectifier module.
