The Diode Clamper: Lift the AC, Keep the Shape

1:03Fortellerstemme
0:00 / 0:00

Positive diode clamper — a series capacitor and a shunt diode shift an AC sine wave upward by its peak so the negative peaks sit at zero, without changing the shape. The capacitor charges once on the first negative half-cycle and then acts as a constant DC offset on every cycle thereafter. Genuine motion in Beat 3: diode highlights, charge dots flow, V_C climbs to V_p, live readout panel. Genuine motion in Beat 4: synchronised scope traces of V_in (centred on zero) and V_out (centred on +V_p) with cursor + offset arrow.
