principle of operation of an inverter

Introduction:

                                 principle of operation of an inverter
    An inverter can be taken as crude form of "UPS" obviously the main use of an inverter is only for powering common electrical appliances like light, fan etc . during power failure 
   As the name implies the basic function of a inverter is to invert an input D.C voltage (12DCV) into a much larger magnitude of alternating voltage (generally 110ACV or 220ACV) 

                         FUNDAMENTAL ELEMENT OF AN INVERTER 

1.OSCILLATOR:  an oscillator converts an input d.c voltage from a lead acid batteryinto a oscillating current or square wave (A.C) which is fed into the secondary winding of a power transformer .

2.TRANSFORMER: Here the applied oscillating voltage is stepped up per ratio of the winding of the transformer and an A.CV  much higher than the d.c source becomes primarily available at the primary winding of the transformer  (output of the inverter) 

3.CHARGER: you can also create a charger  so that during power  backups, when the battery is discharged to a considerable level the charger section is used to charge the battery once the A.C mains is restored

N.B: THIS IS NOT THE FULL INFORMATION TO MAKE AN INVERTER BUT A SCHEMATIC OF WHAT AN INVERTER IS ALL AOUT

How DC motor works and control.

Introduction to DC motors A DC motor is an electric motor that converts direct current electrical energy into mechanical energy. They operate based on the principle of "Force acting on a coil of wire in a magnetic field". This principle states that when a current-carrying conductor is placed in a magnetic field, the conductor experiences a mechanical force. The direction of this force is determined by Fleming's left-hand rule, and the magnitude of the force can be expressed as:                   F= B*I*L ( in newtons) where  F- force(newtons) B- magnetic field (Tesla) I- Current ( Ampere) L- Length of the conductor. According to Fleming's left-hand rule, the direction of the force is perpendicular to both the conductor and the magnetic field.   Tip: if the direction of current flow is reversed, the direction of rotation of the motor changes also. Controlling DC motors DC motors find use in various applications where ope...

Flame Detectors Explained

 Flame sensor/ detectors: Flame detectors(sensors) detect the presence of flame.  just as every other sensor operate ; they detect a change in a physical phenomenon and then produce an output signal proportional to the change in the physical phenomenon being sensed or detected. The presence of fire which relates to flames is a physical condition to be watched against  and since this is an unwanted condition , there arise the need to constantly watch(detect) against it and eliminate it as quick as possible when detected . Flame detectors are devices that watch against flames (fire ) , it may also be called a fire detector.  A flame sensor detects a flame but what physical or measureable characteristics of a flame does it detects??. with this question in mind , we need to overview flames , identify the properties of a flame that can be detected /measured / sensed  and work on the best methodology to detect flames. OVERVIEW OF FLAMES A flame is a mixture of reac...

Astable multivibrator

Astable multivibrator Astable Multivibrators are free running oscillators which oscillate between two states continually producing two square wave output waveforms.            Introduction  Regenerative switching circuits such as  Astable Multivibrators   are the most commonly used type of relaxation oscillator because not only are they simple, reliable and ease of construction they also produce a constant square wave output waveform. Unlike the Monostable Multivibrator or the Bistable Multivibrator we looked at in the previous tutorials that require an “external” trigger pulse for their operation, the  Astable Multivibrator  has automatic built in triggering which switches it continuously between its two unstable states both set and reset. The  Astable Multivibrator  is another type of cross-coupled transistor switching circuit that has  NO  stable output states as it changes from one state to the other all ...
