Kopplingsanordning för strömförsörjning av en styrelektronikenhet i en tvåledareffektkopplare

摘要

The circuit (R) is set between a prestabilising circuit (2) and the regulator's control electronics (4). It has a self-timing control unit (3), an electronic switch (S), a diode (D), a choke (L1) and a storage capacitor (C) The circuit supplies the necessary energy for the control electronics. The control unit's switch preferably maintains the regulator's operation voltage (UB).
