2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   An inverter may produce a square wave, sine wave, modified sine wave, pulsed sine wave, or near-sine pulse-width modulated wave (PWM) depending on circuit design. Common types of inverters produce square waves or quasi-square waves. One measure of the purity of a sine wave is the total harmonic distortion (THD). [4]

3. 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 ...

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. Uninterruptible power supply - Wikipedia

   en.wikipedia.org/wiki/Uninterruptible_power_supply

   The motor side of the unit in case Nos. 2 and 3 can be driven directly by an AC power source (typically when in inverter bypass), a 6-step double-conversion motor drive, or a 6-pulse inverter. Case No. 1 uses an integrated flywheel as a short-term energy source instead of batteries to allow time for external, electrically coupled gensets to ...

6. 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 ...
