<p>A smoothing circuit for electronic power supplies, has low losses independently of fluctuations in input voltage and of the supply of a pulsed output of variable frequency and has a very low internal dynamic resistance, with an adjusting transistor. A transmitter (T1) in an earthed emitter circuit is controlled according to a voltage comparison made by an operational amplifier (J1) between the filtered input voltage (U1) after reduction in a voltage divider and a voltage proportional to the output voltage (U2) derived from a second voltage divider.</p> |
