A rectifier is a device that convertsalternating current(AC) todirect current(DC). It is done by using a diode or a group of diodes. Half wave rectifiers use one diode, while afull wave rectifieruses multiple diodes. The working of a half wave rectifier takes advantage of the fact that ...

Smoothing capacitor isalso calledFilter capacitorand its function is to convert half wave / full waveoutput of the rectifier into smooth DC. Thepower ratingand thecapacitancearetwo important aspects to be considered while selecting the smoothing capacitor.The power rating must be greater than the ...

. B2 terminal of the UJT is made positive with respect to B1 terminal using the voltage source Vbb. Emitter terminal E of the UJT is forward biased using the voltage source Ve. Current starts flowing into the emitter only when the bias voltage Ve has exceeded the forward drop of the ...
“-” sign indicates the bound charge of impurity. In theN-typeregion, the negative “-“ sign indicates electrons which are the majority carriers, and the circled plus “+” sign indicates the bound positive charge of impurity. In the figure, thermally generated minority carriers i.e. holes...

To control both polarities of the ac supply either two SCRs had to be used, con- nected in anti-parallel, or a single SCR inside a full wave bridge rectifier (Ref. 1, Chapter 8 - AC Phase Controlled Circuits). In the 1960s, bidirectional Thyristors, called Triacs, where introduced. ...
