Half wave Rectifier

Recifier Circuit

Half wave rectifier

Circuit Diagram

  • The rectifier circuit cosists of resistive load, rectifying element, i.e. p-n junction diode and the source of a.c voltage, all connected in series
  • To ontain the desired d.c voltage across the load, the a.c voltage is applied to rectifier circuit using suitable step-down, step-up transformer, mostly a step-down one with necessary turns ratio.

Operation of the Circuit

  • During positive half cyle of input a.c voltage, terminal (A) becomes positive with respect to terminal (B). The diode is forward biased and the current flows in the clockwise direction. This current is also flowing through the load resistance RL hence denoted as IL(load current).
    1. During negative half cycle when terminal (A) is negative with respect to terminal (B), diode becomes reverse biased. Hence no current flows.
    2. Thus the circuit, which is also the load current, is in the form of half sinusoidal pulses
      • The load voltage, being the product of load current and load resistance, will also be in the form of half sinusoidal pulses.

    Miller Crystal Oscillator

    Miller Crystal Oscillator Miller Crystal Oscillator Similar to modifications in Colpitt's oscillator, the Hartley oscillator circuit can be modified, to get Miller crystal Oscillator In Hartley oscillator circuit, two inductors and one capacitor is required in the tank circuit. One inductor is replaced by the crystal which acts as an inductor for the frequencies slightly greater then the series resonant frequency. The tuned circuit of L1 and C is offtuned to behave as an inductor i.e. L1. The crystal behaves as other inductance L2 between base and ground. the Internal capacitance of the transistor acts as a capacitor required to fullfill the elements of the tank circuit The crystal decides the operating frequency of the oscillator.
