Disclosed is a method and apparatus. The method includes detecting an operating state of a current source converter that comprises a current source rectifier (), a current source inverter (), and an inductor circuit () connected between an output (p, n) of the current source rectifier () and an input (q, r) of the current source inverter (); and dependent on the detected operating state, operating the current source converter in a first operating mode or a second operating mode. Operating the current source converter in the first operating mode comprises operating the current source rectifier () in a 2/3 mode and operating the current source inverter in a 3/3 mode, and operating the current source converter in the second operating mode comprises operating the current source inverter () in the 2/3 mode and operating the current source rectifier in the 3/3 mode.

Method for operating a current source converter, control circuit, and current source converter

A monolithically integrated bidirectional switch includes: an output terminal; a control terminal; a compound semiconductor substrate; a common drift region in the compound semiconductor substrate and in series between the input terminal and the output terminal; a first gate; and a second gate. The first gate is electrically connected to the control terminal and the second gate is electrically connected to the input terminal, or one of the first gate and the second gate is a normally-on gate and the other one of the first gate and the second gate is a normally-off gate. In either case, the monolithically integrated bidirectional switch is configured to conduct current in a single direction from the input terminal to the output terminal through the common drift region. A corresponding power electronic system that uses the monolithically integrated bidirectional switch is also described.
