摘要：The invention relates to a circuit assembly for de-excitation of an excitation coil(E) of a synchronous machine in case of an error having a control circuit (1) for controllinga current flow through the excitation coil (E), wherein a positive control voltage can beapplied to the excitation coil (E) for excitation and a negative control voltage can beapplied for fast de-excitation, and a protection circuit (10) connected in parallel to theexcitation coil (E) which allows no current flow via the protection circuit (10) in the case offast de-excitation and in case of interruption of at least one connection line between thecontrol circuit (1) and the excitation coil (E) forms a current path for voltage limiting andde-excitation of the excitation coil (E).
