Dc traction power
WebThis 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. Many modern trams and trains use on-board solid-state electronics to convert these supplies to run three-phase AC traction motors. WebWhen it comes to rail infrastructure, the key focus areas are DC and AC traction power supply applications. Our innovative products are designed for heavy-duty traction …
