D.C Power Supplay Stages

The block diagram of d.c power supply

  • A typical d.c power supply consists of varies stages. The block diagram of d.c power supply consisting of varies circuit.

    • 1.Transformer

  • The a.c voltage(230v,50Hz) is connected to the primary of the transformer. The transformer steps down the a.c voltage, to required for the desired d.c voltage output. Thus, with suitable turns ratio we get desired a.c voltage

    • 2.Rectifier Circuit

  • The rectifier circuit converts this a.c voltage into a pulsating d.c voltage. A pulsating d,c voltage means a undirectional voltage containing large varying component called ripple in it

    • 3.Filter circuit

  • The filter circuit is used after a rectifier circuit, which reduses the ripple content in the pulsating d.c tries to make it smoother. Still then the filter output contains the some ripple. The voltage is called unregulated

    • 4.Regulator circuit

  • A circuit used after the filter is a regulator circuit. The ouput of a regulator is called regulated smooth d.c supply, to which load can be connected

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.

Electronic oscillator division types and use Electronic oscillator division types and use Introduction to oscillator An oscillator is a amplifier and it is a close loop circuit or network. It uses the Positive feedback. It is not require the externel signel and generate the a desired frequency A oscillatpr acts like generator, It oscillates the constant amplitude and frequency. Oscillator can generate the frequency upto gigahertz. Classification of the Oscillators Oscillators are classified based on the type of waveforms generate from the oscillator, range, frequency, parameters used. Based on Output waveforms. Based on circuit components. Range of operating frequency. Based on feedback uses or not uses Types of oscillatprs LC Oscillator Har...
