2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Sine wave. A power inverter device that produces a multiple step sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish the inverters with outputs of much less distortion than the modified sine wave (three-step) inverter designs, the manufacturers often use the phrase pure sine wave inverter.

3. Resonant inverter - Wikipedia

   en.wikipedia.org/wiki/Resonant_inverter

   This type of inverter produces an approximately sinusoidal waveform at a high output frequency, ranging from 20 kHz to 100 MHz, and is commonly used in relatively fixed output applications, for example, induction heating, sonar transmitters, fluorescent lighting, or ultrasonic generators. Due to the high switching frequency, the size of the ...

   If more than two voltage levels were available to the inverter output terminals, the AC output could better approximate a sine wave. It is for this reason that multilevel inverters, although more complex and costly, offer higher performance. [18] Each inverter type differs in the DC links used, and in whether or not they require freewheeling ...

5. Variable-frequency drive - Wikipedia

   en.wikipedia.org/wiki/Variable-frequency_drive

   Small variable-frequency drive Chassis of above VFD (cover removed). A variable-frequency drive (VFD, or adjustable-frequency drive, adjustable-speed drive, variable-speed drive, AC drive, micro drive, inverter drive, variable voltage variable frequency drive, or drive) is a type of AC motor drive (system incorporating a motor) that controls speed and torque by varying the frequency of the ...

6. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   Inverters that target commercial applications are available for 208, 240, 277, 400, 480 or 600 VAC and may also produce three phase power. Peak efficiency: The peak efficiency represents the highest efficiency that the inverter can achieve. Most grid-tie inverters on the market as of July 2009 have peak efficiencies of over 94%, some as high as ...
