Q. What is positive clipper? Give 2 types of its applications ?
In the series positive clipper, when the input voltage is positive, the diode does not conduct and acts an open circuit and hence the positive half cycle does not appear at the output, that is the positive half cycle is clipped off. When the input cycle is negative, the diode conducts and acts as a closed switch (short circuit), the negative half cycle appears at the output.
In the stunt positive clipper, when the input voltage is positive, the diode conducts and acts as a short-circuit and hence there is zero signal at the output, i.e. the positive half cycle is clipped off. When the input signal is negative, the diode does not conduct and acts as an open switch, the negative half cycle appears at the output.
It is evident that positive clippers introduce as half wave rectifier. Thus the positive clipper has clipped the positive half cycle completely and allowed to pass the negative half cycle of the input signal.
why the primary bushing of 7970/13.8 distribution transformer blown up when connected wye on a 13.8 kv source?
