2. 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.

3. Grid-tie inverter - Wikipedia

   en.wikipedia.org/wiki/Grid-tie_inverter

   A grid-tie inverter converts direct current (DC) into an alternating current (AC) suitable for injecting into an electrical power grid, at the same voltage and frequency of that power grid. Grid-tie inverters are used between local electrical power generators: solar panel, wind turbine, hydro-electric, and the grid. [1]

4. Deregulation of the Texas electricity market - Wikipedia

   Nationwide data from the U.S. Energy Information Administration [7] shows that Texas's electric prices did rise above the national average immediately after deregulation from 2003 to 2009, but from 2010 to 2015, prices dropped significantly below the national average price, with a total cost of $0.0863 per kWh in Texas in 2015 vs. $0.1042 ...

5. Power inverter - Wikipedia

   en.wikipedia.org/wiki/Power_inverter

   Utility frequency conversion - if a user in (say) a 50 Hz country needs a 60 Hz supply to power equipment that is frequency-specific, such as a small motor or some electronics, it is possible to convert the frequency by running an inverter with a 60 Hz output from a DC source such as a 12V power supply running from the 50 Hz mains.

6. 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 ...

7. Electric power conversion - Wikipedia

   en.wikipedia.org/wiki/Electric_power_conversion

   Operating at high frequency and supplying low power, power converters have much smaller transformers compared with those of fundamental-frequency, high-power applications. The current in the primary winding of a transformer help to sets up the mutual flux in accordance with Ampere's law and balances the demagnetizing effect of the load current ...
