Some can convert single-phase power to three-phase power and vice versa. Variations can input or output DC power to reduce the number of conversions, for greater end-to-end efficiency. A Modular Solid-state transformer consists of several high-frequency transformers [1] and is similar to a Multi-level converter. As a complex electronic circuit ...
The static converters in the system were commissioned during the decade between 1992 and around 2002. Static converters use high-power solid-state electronics with few moving parts. Chief advantages of static converters over motor generators include lower capital cost, lower operating costs, and higher conversion efficiency.
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.
A frequency changer or frequency converter is an electronic or electromechanical device that converts alternating current of one frequency to alternating current of another frequency. The device may also change the voltage , but if it does, that is incidental to its principal purpose, since voltage conversion of alternating current is much ...
All 25 Hz power on the ex-Reading system is generated at the Wayne Junction static converter plant. This plant was built between 1985 and 1990 and consists of three 15 MVA solid-state, cycloconverter-based modules. The system was built by ASEA and is similar technically to the converter later installed at Amtrak's Jericho Park converter.
Investors piled into NuScale stock, sending it more than 6% higher in price across the trading session. By comparison, the benchmark S&P 500 index only managed to rise 0.8% that day. Google gets ...

[42] [43] In addition, newer installations include a DC-DC converter, a solid-state device that converts the high-voltage traction motor energy to 12/24V accessory power. [42] As of 2008, there are more than 2,700 GM-Allison hybrid buses operating in 81 cities in the U.S., Canada and Europe. [41] This includes: Translink (Vancouver) Dresden ...
