SCR VI Characteristics
... Theory: An SCR is a device which can be turned on through the gate pulse and turned off using power circuit i.e., turn on is controlled but turn off is uncontrolled in an SCR. The voltage at which the SCR gets into conduction state is called forward breakover voltage(VBO). If the gate current is inc ...

... 1. It may be observed from the equation given earlier that, as the inverter frequency ( f = 1 / T ) is increased, the turn-off time provided by the circuit decreases. But, the circuit commutation time, t off , should be more than the turn-off time of the thyristor, t q , for reliable operation. This ...

When connected in forward bias its resistance is very low (provided it has a potential difference of more than 0.6 volts across it). The diode has a very high resistance in the reverse bias therefore on ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
