What is Bleeder Resistor? - Working and Its Functions The operation of an inductor filter is based on the fact that a minimum current flows through it at all times. To provide flow of this…
What is Surge Current? - Definition and Workings Before switching on of power supply, the filter capacitor is uncharged [Fig. 9.23]. At the instant the power supply is switched on, the uncharged capacitor behaves like…
Baritt diode - Working and Applications: The barrier-inject transit time (BARITT) diode is basically a back-to-back pair of diodes biased into reach-through condition. It belongs to the transit-time microwave diode family. In this diode microwave…
What is a thermistor? - Definition, Symbol and V-I Characteristics: The word thermistor is a combination of thermal and resistor. A thermistor is a resistor with definite thermal characteristics. Most thermistors have a negative temperature…
Varistors or Voltage Dependent Resistors (VDRS): Varistors, also called the voltage dependent resistors (VDRs), show a high degree of nonlinearity between their resistance value and the applied voltage. They are made of non-homogeneous materials giving…
Power Diode - Structure, Symbol, Characteristics and Types: Diodes find many applications in electronics and electrical engineering circuits. Power diodes play a significant role in power electronics for conversion of electric power. A diode acts…
What is Backward Diode? A tunnel diode designed to provide a small peak current (IP of the order of IV) may be employed to advantage in the reverse direction, for purposes for which the conventional…
What is Schottky Diode? - Definition, Symbols and Construction: At lower frequencies, an ordinary diode can easily turn off when the bias changes from forward to reverse. But with the increase in frequency the diode…
Fast Recovery Diode (FRD): Fast recovery diode are designed to provide ultrahigh switching speed. The devices can be classified into two types : diffused P-N junction diodes and metal semiconductor diodes. The equivalent circuit of…
What is Step Recovery Diode? - Working and Applications: What is Step Recovery Diode? - It is also a voltage dependent variable capacitor diode but with unusual doping profile. It has concentration of charge carriers…
