2. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

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. 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 ...

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 ...

6. Electrosurgery - Wikipedia

   en.wikipedia.org/wiki/Electrosurgery

   Electrosurgery is the application of a high-frequency (radio frequency) alternating polarity, electrical current to biological tissue as a means to cut, coagulate, desiccate, or fulgurate tissue. [1][2][3][4][5][6][7] (These terms are used in specific ways for this methodology—see below.) Its benefits include the ability to make precise cuts ...
