2. Programmable load - Wikipedia

   en.wikipedia.org/wiki/Programmable_load

   Most commercial DC loads are equipped with microprocessor front end circuits that allow the user to not only program a desired current through the load ('constant current' or CC), but the user can alternatively program the load to have a constant resistance (CR) or constant power dissipation (CP).

3. Pre-charge - Wikipedia

   en.wikipedia.org/wiki/Pre-charge

   Precharging a high voltage DC power distribution line can control the inrush current into capacitive components, reducing stress and supporting a long component life. The functional requirement of the high voltage pre-charge circuit is to minimize the peak current out from the power source by slowing down the dV / dT of the input power voltage ...

4. Power electronics - Wikipedia

   en.wikipedia.org/wiki/Power_electronics

   Power electronics is the application of electronics to the control and conversion of electric power. The first high-power electronic devices were made using mercury-arc valves. In modern systems, the conversion is performed with semiconductor switching devices such as diodes, thyristors, and power transistors such as the power MOSFET and IGBT ...

5. High-voltage direct current - Wikipedia

   en.wikipedia.org/wiki/High-voltage_direct_current

   Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

9. Boost converter - Wikipedia

   en.wikipedia.org/wiki/Boost_converter

   Power for the boost converter can come from any suitable DC source, such as batteries, solar panels, rectifiers, and DC generators. A process that changes one DC voltage to a different DC voltage is called DC to DC conversion. A boost converter is a DC to DC converter with an output voltage greater than the source voltage. A boost converter is ...
