2. Shunt clippers

In Shut clippers, the diode is connected in parallel with the source.

a. Shunt positive clipper circuit

The shunt positive clipper circuit operation is opposite the series positive clipper. The diode connect the circuit in parallel to load. The positive half cycle the diode is forward bias the output voltage is zero.

3. Dual clipper circuit (or) combination circuit with biasing

The combination of circuit it means the series and shunt (or) positive clipper and negative clipper operation performed. So it also called as “Dual clipper”. Both positive and negative cycles are absence in the clipper.

Fig.9.Dual clipper circuit

During positive half cycle the (D1) diode forward biased due to shunt connection the output going to zero. The corresponding supply voltage (V_B1) forward biased to the (D1) diode to obtain output voltage (V_B1).

During negative half cycle the (D2) diode reverse biased due to shunt connection the output are going to zero. The corresponding supply voltage (V_B2) forward biased to the (D2) diode to obtain output voltage (V_B2).
