Abstract:
A circuit arrangement havinga half-bridge arrangement comprising a first and a second switch (T1;T2), each switch (T1;T2) having, between its operating and reference electrodes, an internal diode (DB1;DB2), which is reverse-connected in parallel with the main current flow direction of the respective switch (T1;T2), and also an internal capacitance (C.sub.OSS 1;C.sub.OSS 2) a series diode (DS1;DS2) being arranged in series with the respective switch (T1;T2) in the main current flow direction in such a way that current can flow in the main current flow direction, and a freewheeling diode (DF1;DF2) being connected in parallel with the respective series circuit formed by the switch (T1;T2) and the series diode (DS1;DS2), anda load circuit (L;RL), which has at least one inductive component (L) and is connected to the midpoint of the half-bridge arrangement,wherein a load-relieving capacitance (CE1;CE2) is connected in parallel with each series diode (DS1;DS2).
