<p>A circuit (30, 40) for the separate potential generation of an output voltage (Vout) originating from a mains voltage (Vin) is proposed, comprising - a power factor correction circuit (31) with an inductor (L31) supplied by the mains voltage (Vin) and a controllable switch (T31) for controlling the charging and discharging of the inductor (L31), and - at least one potential separating transformer (N1- N2, N1'-N2') for the electrical isolation of the output voltage (Vout) to the mains voltage (Vin), wherein during the discharge of the inductivity (L31) a first part of the energy stored by the inductor (L31) during charging is directly fed to the potential separating transformer (N1- N2, N1'-N2').</p> |
