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 ...
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 ...
The Jericho Park converter exceeds its efficiency design criteria of 95%. Major disadvantages of solid state converters include harmonic frequency generation on both the 25 Hz and 60 Hz sides, and lower overload capability. Sunnyside Yard (Long Island City), NY – Static Inverter rated at 30 MW ordered from ABB in 1993 for $27 million. This ...
This is a list of the power supply systems that are, or have been, used for railway electrification. Note that the voltages are nominal and vary depending on load and distance from the substation. As of 2023 many trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors.
