Schematic Circuit Diagram:
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.
