As we know, both Snubber Circuit and Crowbar Circuit is used for protection against Overvoltage using Thyristor but they way they protect the Thyristor has some difference. Crowbar Circuit: Power supplies are normally reliable, but if they fail then they can cause significant damage to the circuitry they supply. To protect against this it is … Read more Difference between Snubber Circuit and Crowbar Circuit
Step potential is the voltage between the feet i.e. one step of a person standing near an energized grounded object. Touch potential is the touch voltage between the energized object and the feet of a person in contact with the object. It is equal to the difference in voltage between the object and a point … Read more Step Potential and Touch Potential – Must Read
SCR / Thyristor is a four layer three junction device. It mainly consists of interleaved layers of P and N layers. It can block Voltage of either polarity but conducts current only in one direction that is from Anode to Cathode under normal working of forward biasing. Basically to forward bias an SCR we need … Read more What Happens When Reverse Biased Thyristor Gated?
First we will describe what avalanche breakdown is. Avalanche breakdown occurs at p-n junction which is moderately doped and has a thick junction means have depletion layer width high. Avalanche breakdown occurs when we apply high reverse voltage across the p-n junction. As we apply more and more reverse voltage across the junction, the electric … Read more Avalanche Breakdown of Thyristor
DC – DC Booster: Booster converter is a combination of Transistors, diodes, and/or inductor or capacitor. The combination of active electronic elements (diodes and transistors) provides a DC voltage step up (say 1.5 to 9 v) while the combination of passive elements acts as a filter to reduce ripples. Its basic function is to step … Read more Difference between DC-DC Booster and Chopper
