need how PWM can be implemented in inverter and charge controller circuit. If you have circuit that would be greate. What is the difference in using the PWM and not using the PWM circuit on inverter.
In case of DC-AC inverter if u use PWM then the output will remain constant as load variation happens. if not then output will decrease as load increase and vice versa.

Check the internal circuitry of LM3524 for the PWM, however I will suggest that you consult some basic book like "Electronics Principle by Albert Paul Malvino" or Switch Mode Power Supply book. (some are avalible in this forum, search).
Hi,
An inverter generates AC signal from DC. So, I do not think it needs to use PWM since an AC is expected to to be a symmetric wave form.
A PWM signal contains DC value embedded in it as average value, but can be coupled using transformers as if it is an AC signal. In DC switching power supplies and in DC/DC converters, PWM can be used to regulate the output DC voltage by adjusting the width of the pulse in a feedback loop.
You can also refer to the site www.irf.com of International Rectifiers for more info.

PWM ( Pulse Width Modulation )... much like a CHOPPED square wave.. either single-ended or push-pull... uses transistors/MOSfets ....driving a ferrite core transformer.. used to step UP or DOWN the input voltage OR simply to generate a SPECIFIC output voltage...
the simplest form of PWM controllers (w/c I have used) are TL494 and SG2525... been using them for DC-DC converters....the more elaborate PWM controllers use uControllers to generate PSEUDO SINE waves for AC inverters...
try to download datasheet(PDF) files of the mentioned chips..and understand it...Helping yourself is best for learning!
