Here, inverter converts DC to AC, then a transformer is used to convert it back into DC. Converters can be used for DC-DC conversion. ![]() They are also used to supply polarized voltage for welding. They are also used to detect amplitude modulated radio signals. Virtually all the electronic devices require converters. Most of the AC products run on modified sine wave inverters since they are comparatively less expensive.Ĭonverters are used to convert AC power to DC power. True/Pure Sine wave inverters: These are the most expensive form of inverters.It costs less and is more effective than square wave. It works for all pure loads like lamps or heaters. This reduces the distortion or harmonics that causes problems with electrical devices. Modified square wave has a step or dead space between the square waves. Quasi wave or Modified square wave inverters: As the name suggest, the wave form is square, and not sinus as required to have pure sine wave AC.It is the least expensive inverter but it produces low quality power. ![]() The switches can withstand heavy current flow. It consists of a DC source, four switches and the load. Square wave inverter: This is a type of inverter which produces a square wave output.Digital-to-digital converter (DDC) is a device which converts one type of digital data to another type of digital data.DAC are found in CD players, digital music players and PC sound cards. ![]()
