DC-AC Converter

• The DC/AC converters are also known as inverters where a fixed DC voltage source is converted in AC source. A inverter changes direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.

Control MethodsSquare wave:The square wave output has a high harmonic content, not suitable for certain AC loads such as motors or transformers. Square wave units were the pioneers of inverter development

Control MethodsPure sine wave:A pure sine wave inverter produces a nearly perfect sine wave output that is essentially the same as utility-supplied grid power. Thus it is compatible with all AC electronic devices. Its design is more complex, and costs more per unit power.
