WEEK 6

TITLE OF ACTIVITY : Pulse width modulation.

OBJECTIVES : 
-To understand the basic operation of the inverter.

METHODS :
-Make observations about the sources and basic functions.
-Collect all the details fit.
-Search data sheets on the internet.

PIN CONNECTIONS OF SG3526

RESULT :
-More on observation by our gathering data.


Analysis :
-The basic operation of the power
inverter is illustrated in Figure 1.
The SG3526 alternately switches the
current through the 12-V windings of
a mains transformer, the two central
ends of the windings having been
taken together and connected to the
positive battery terminal (+12 V). At
each switching action, the direction
of the current changes and with it
the direction of the magnetic field in
the transformer core. The result is a
square-wave(-like) alternating voltage
at the 230-V side of the transformer.





CONCLUSION :
-Initial data collection is finally finished.
