What is Inverter: Definition and 174 Discussions

A power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of "converters" which were originally large electromechanical devices converting AC to DC.The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.
A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.
Static inverters do not use moving parts in the conversion process.
Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators. Circuits that perform the opposite function, converting AC to DC, are called rectifiers.

    Problems with Inverter and transformer

    Hi, i am building an inverter 12VDC- 120VAC, 50 Hz with square wave as gate signal for MOSFET. Looks like my circuit works fine because i am getting square out -12 to 12 AC. Now i am using transformer to step up 12 VAC to 120 VAC. But i am experiencing some problems. But i am supplying...

    DC to AC Inverter Design Difficulty

    Hey Guys, I'm having trouble designing an inverter to power an ac motor using a fuel cell with MATLAB. With the inverter, the output current of the DC converter dips below 0 and the fuel cell does not like that at all because it causes a 'ln of -ve number' error. I have tried placing an...

    Simple inverter schematic? (Solid state, no coil.)

    I was wondering if there is a simple way to make a power inverter (DC to AC) that is solid state, and does not use a coil. Actually, I'm not sure if there is a difference, but "pulsing DC" might be more what I'm thinking. I don't necessarily need the current to flow in reverse, but just to...

    Bidirectional pure sine wave inverter

    Hello All: A project of mine requires a bi-directional inverter that will take a 12VDC (most likely) battery to single phase 120VAC pure sine wave for utility tie (mains power). I will also require the inverter to be able to rectify to utility's power to charge the battery as well. Since...
