Introduction
Inverters convert DC electricity into AC electricity. Many different types of inverters are available as they vary in power, efficiency and function. Inverters are typically used to draw power from one or more 12 V batteries and convert it into 120 V AC at 60 Hz - for use in ordinary household outlets.
Design Considerations
The power produced by inverters is usually one of two types:
Modified Sine Wave - Similar to sine wave, but waveform is rectangular rather than rounded. While the simpler design of these inverters are less expensive many devices will not work properly with power using a modified sine wave, such as televisions and computers.
Pure Sine Wave - Accurately simulates the sine wave power. They are usually employ more complicated circuitry and are more expensive. They can be used with any common AC device.
Inverter Design
Inverter designs typically employ the following elements:
Oscillator - provides a reference waveform for comparing the output waveform and creating feedback.
Driver circuit - with feedback
