Abstract (en)
[origin: EP0556652A2] To switch a load (2), a hybrid switch is provided which contains a first semiconductor switch (4) with a commutation switch (7). According to the invention, the commutation switch (7), which bypasses at least the first semiconductor switch (4), is associated with a magnetic drive (10) with a first magnetic coil (11) through which the short-circuit current flows, and a second semiconductor switch (5) which is connected, in series with a second magnetic coil (12), in parallel with the series circuit of the first magnetic coil (11) and the load (2). <IMAGE>
