Inverter Circuits
The articles discussed below present a mammoth collection of DC to AC inverters and converters with many different specifications and toplology.
We have many simple versions designed to work with small batteries such as 12V 7Ah batteries to produce around 100 to 500 watts 220V AC, and also the gigantic ones which are conditioned to generates awesome amounts of power in the range of 1000 to 5000 watts.
Since all these converters primarily utilize battery power for converting lower 12V to 24V DC to 120V or 220V AC, it becomes mandatory for these systems to employ a battery charger system also, without which consistent functioning of the units can become impossible.
The following articles include specialized battery charger circuits which can be used for reliable recharging of batteries and for using them in the converter applications.
When we talk about DC/AC converters we basically refer to the various inverters and their topologies. An inverter is a device that converts power from a low DC source to a high AC level.
The low voltage DC source could be from a battery or a solar panel or any other option having the capacity to generate high current low voltage DC.
The word inverter arises from the function of the unit wherein it inverts the low voltage DC into a high voltage AC using a transformer.

Pure Sinewave Inverters
The best Pure sinewave inverters will technically produce an output that will have its waveform closely matched like a sinewave. In the above PWM sinewave, the output might not be too effective in replicating a sinewave, but a pure sinewave inverter will do it perfectly and allow the inverer to produce a pure sinewave output.
These inverters therefore become very suitable for powering sensitive and critical electronic equipment such as many medical related equipment, amplifiers, computers, TV and laptops.
This website is the first of its kind to present reasonably good quality pure sinewave inverters which can be actually built by any newcomer in the filed and make him feel proud experience.

Solar Inverters
As the name suggests a solar inverter is a device that converts DC electricity from a solar panel into AC mains 220V or 120V for powering the connected appliances. Actually solar inverters are ordinary inverters which are integrated with solar panels for doing the same job that they were assigned to do with batteries.
Alternatively solar inverters are also used for charging batteries from the solar panel during day time and then using the charged battery for powering homes and appliances during night.
In this website you will see a good variety of solar inverter circuits which are actually regular inverters but attached with solar panels for the required outputs.

Ferrite Core Inverters
Ferrite Core inverter circuits are made using ferrite core for the transformer instead of the conventional iron core transformers. The main benefit of using ferrite core instead of iron core is that the inverter become extremely compact, streamlined, lightweight, more powerful and hugely efficient.
However the downside is that ferrite inverters are equivalently more complex to build than iron core inverters, because of the fact that ferrite cores require a high frequency in the order of 20 to 100kHz to operate and produce the specified efficient outcomes.
Since the final required output from the inverter needs to be at a a comparatively lower 50Hz or 60Hz frequency, the high frequency operation becomes incompatible for a direct use with the appliances. To counter this ferrite inverter topologies have to first convert this high frequency inverter output into DC, and then again convert this DC into a 50/60Hz output with a PWM processing.
All these procedures ultimately compels the unit to become highly complex with its design.
No worries, even though it might look complex from outside, here I have tried my best to unfold the various stages of a ferrite core inverter concept that would allow the new hobbyists to learn the intricacies of these inverters through straightforward layouts and explanations.
