2. Inverter compressor - Wikipedia

   en.wikipedia.org/wiki/Inverter_compressor

   Before, fixed-speed on/off compressors required an inrush, or surge, current that was 4 to 6 times greater than the running current at startup, meaning a requirement of 4 to 6 times more solar panels or batteries. Inverter compressors start slowly and avoid this startup power which is needed each time a standard on/off compressor comes on.

3. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   The AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving. This allows the inverter to power numerous devices designed for standard line power.

4. Rotary converter - Wikipedia

   en.wikipedia.org/wiki/Rotary_converter

   1909 500 kW Westinghouse rotary converter. A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter.. Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting.

5. Power electronics - Wikipedia

   en.wikipedia.org/wiki/Power_electronics

   In power distribution networks, AC/AC converters may be used to exchange power between utility frequency 50 Hz and 60 Hz power grids. DC/AC converters are used primarily in UPS or renewable energy systems or emergency lighting systems. Mains power charges the DC battery. If the mains fails, an inverter produces AC electricity at mains voltage ...

6. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   In electrical engineering, power conversion is the process of converting electric energy from one form to another. A power converter is an electrical device for converting electrical energy between alternating current (AC) and direct current (DC). It can also change the voltage or frequency of the current.

7. AC-to-AC converter - Wikipedia

   en.wikipedia.org/wiki/AC-to-AC_converter

   An AC-AC converter with approximately sinusoidal input currents and bidirectional power flow can be realized by coupling a pulse-width modulation (PWM) rectifier and a PWM inverter to the DC-link. The DC-link quantity is then impressed by an energy storage element that is common to both stages, which is a capacitor C for the voltage DC-link or ...

8. Synchronization (alternating current) - Wikipedia

   en.wikipedia.org/wiki/Synchronization...

   In an alternating current (AC) electric power system, synchronization is the process of matching the frequency, phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are synchronized.

9. Inverter (disambiguation) - Wikipedia

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

   A power inverter is a device that converts direct current to alternating current. Inverter may also refer to Inverter (logic gate) or NOT gate, a device that performs a logical operation; Inverter air conditioner, a type of air conditioner that uses a power inverter to vary the speed of the compressor motor to continuously regulate temperature
