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. [2]

3. Inverter (logic gate) - Wikipedia

   en.wikipedia.org/wiki/Inverter_(logic_gate)

   Voltage transfer curve for a 20 μm inverter fabricated at North Carolina State University. Digital inverter quality is often measured using the voltage transfer curve (VTC), which is a plot of output vs. input voltage. From such a graph, device parameters including noise tolerance, gain, and operating logic levels can be obtained.

   The product of the direct voltage and the direct current (mean values). DC ripple factor The ratio of half the difference between the maximum and minimum value of a pulsating direct current to the mean, value of this current. [m] direct AC/DC converter An electronic AC/DC converter without a DC or AC link. direct AC converter

   root mean square The root mean square value of a waveform is the DC value that corresponds to equivalent heating value. rotary converter An electric machine that converts electric power between two forms, say, AC and DC or single-phase and three phase, or between two different frequencies of AC (the latter two can be performed by the same machine).

6. Wikipedia:Cleanup Taskforce/String inverter - Wikipedia

   en.wikipedia.org/.../String_inverter

   Simply put, a string inverter is a device for converting DC to AC power and which is designed for high voltage DC inputs. Using a string inverter, the solar panel array, still typically rated at 12V, 24V or 48V each panel (although higher voltage panels are now coming out) is wired in series, rather than in parallel.

7. 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 ...

8. Diode–transistor logic - Wikipedia

   en.wikipedia.org/wiki/Diode–transistor_logic

   NPN based circuits used +6V and -6V and the transistor switched at close to -6V, PNP based circuits used 0V and -12V and the transistor switched at close to 0V. Thus for example a NPN gate driven by a PNP gate would see the threshold voltage of -6V in the middle of the range of 0V to -12V.

9. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   Some supplies use current limiting instead of cutting off power if overloaded. The two types of current limiting used are electronic limiting and impedance limiting. The former is common on lab bench power supplies, the latter is common on supplies of less than 3 watts output.
