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

   The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity power factor, which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The ...

4. Alternating current - Wikipedia

   en.wikipedia.org/wiki/Alternating_current

   The abbreviations AC and DC are often used to mean simply alternating and direct, respectively, as when they modify current or voltage. [ 1 ] [ 2 ] The usual waveform of alternating current in most electric power circuits is a sine wave , whose positive half-period corresponds with positive direction of the current and vice versa (the full ...

5. 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 ...

   If more than two voltage levels were available to the inverter output terminals, the AC output could better approximate a sine wave. [17] For this reason multilevel inverters, although more complex and costly, offer higher performance. [18] A three-level neutral-clamped inverter is shown in Figure 10.

7. Exide Industries - Wikipedia

   In 1997, Exide Industries filed a lawsuit against Exide Technologies of the United States when the latter tried entering the Indian market, and both companies entered a prolonged legal battle that was heard by the Delhi High Court, which led to a 2012 verdict that Exide Industries was the legal owner of the Exide trademark in India.

8. Glossary of power electronics - Wikipedia

   In inverter operation, the situation that a valve arm continues conduction at the end of the normal conduction interval or at the end of the hold-off interval. (electronic) (power) conversion Change of one or more of the characteristics of an electric power system essentially without appreciable loss of power by means of electronic valve devices .

9. 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 ...
