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. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. [1] To inject electrical power efficiently and safely into the grid, grid-tie inverters must accurately match the voltage, frequency and phase of the grid sine wave AC waveform.

4. Solar inverter - Wikipedia

   en.wikipedia.org/wiki/Solar_inverter

   Internal view of a solar inverter. Note the many large capacitors (blue cylinders), used to buffer the double line frequency ripple arising due to single-phase ac system.. A solar inverter or photovoltaic (PV) inverter is a type of power inverter which converts the variable direct current (DC) output of a photovoltaic solar panel into a utility frequency alternating current (AC) that can be ...

5. Harmonics (electrical power) - Wikipedia

   en.wikipedia.org/wiki/Harmonics_(electrical_power)

   In many non-linear loads such as inverters, AC voltage controllers and cycloconverters, the output voltage(s) waveform(s) usually has half-wave symmetry and so it only contains odd harmonics. The fundamental component is an odd harmonic, since when k = 1 {\displaystyle k=1} , the above formula yields h = 1 {\displaystyle h=1} , which is 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 ...

7. Sine wave - Wikipedia

   en.wikipedia.org/wiki/Sine_wave

   Tracing the y component of a circle while going around the circle results in a sine wave (red). Tracing the x component results in a cosine wave (blue). Both waves are sinusoids of the same frequency but different phases. A sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine ...
