Circuit arrangement for pre-charging capacitor supplied by current converter has semiconducting switch per current converter phase in series with phase-related converter diodes

摘要

The circuit arrangement has a semiconducting switch (20) per phase of the current converter that can be turned off, that is connected electrically in series with the phase-related current converter diodes (SR1-SR6) and that is combined on the control side with a rising edge controller (22). AN Independent claim is also included for the following: a method of operating an inventive circuit arrangement.
