Components required
Components required:-

  • Two 68uf 25v tantalum capacitor.(C1,C2)

  • Two 10 ohm, 5 watt Resistor.(R1,R2)

  • Two 180 ohm, 1 watt Resistor.(R3,R4)

  • Two 1N4007 Silicon Diode.(D1,D2)

  • Two 2N3055 NPN Transistor.(Q1,Q2)

  • One 24v Centre tapped Transformer.(T1)

  • Other requirements like wire ,case etc.



Working of d c to a c inverters
Working of D.C to A.C Inverters:

  • Electromagnetic induction is the main underlying principle in the working of the dc to ac inverters.

  • The Transistors Q1,Q2 and the Transformer T1 determine the power output of the inverter.

  • The bigger the Transformer and more powerful the Transistors the more power output is obtained.

  • The inverter requires steady supply of current which is provided by the Lead-Acid Batteries(as it operates at high wattages).


  • The inverters use electro mechanical

    switch , to immediately switch to the mode

    of discharging circuit of the inverter as

    soon as there is a power cut.

  • This technique uses electro magnetic force

    to either make or break the circuit, i.e to

    switch it on or off.


  • Within the Transformer, there are two coils

    namely primary and secondary coils.

    Number of turns in each of these coils is

    significant .

    let the number of turns in and e.m.f of the

    primary and secondary coils be N1,E1 &

    N2,E2;


Then they satisfy the relation :

E2= -(N2/N1)E1

On the basis of the above relation ,the

voltage output is determined.


NOTE: Tantalum capacitors are used instead

of other capacitors because they do

not have regular electrolytes which

possibly over heat and explode.
