Abstract
A method is disclosed for operating a two-phase rotary current controller. In order to optimize the operation of a two-phase rotary current controller, magnitudes of a parameter that can be varied in both controllable phases of a two-phase rotary current controller is matched in these phases. In particular, the existing principle of phase-symmetric control with a uniform ignition delay in both controlled outer conductors is abandoned, and a separate ignition delay is stipulated for each of the two controlled outer conductors.
