The main reason for this biasing is to eliminate charge carriers from the CB-junction. The collector terminal of the NPN transistor is to collects electrons that are emitted through the emitter terminal whereas, in the PNP transistor, it gathers holes that are emitted through the emitter terminal...
Power Electronic Switching components like BJT,MOSFET,IGBT,SCR,TRIAC, etc. are essential devices used in the design of many circuits ranging from a simple driver circuit to complex Power rectifiers and Inverters. The most basic of them all is the BJT, and we have already learnedthe working of...
driven by signals from an external sources like microcontroller, is used to drive the MOSFET. When the transistor is switched off, the MOSFET gets the supply and is switched ON, thus providing proper biasing to the LED array.
Biasing is referred to provide resistors, capacitors, or supply voltage, etc to provide proper operating characteristics of the transistors. DC biasing is used to obtain the DC collector current at a particular collector voltage. The value of this voltage and current are expressed in terms of the...
