2. Buck converter - Wikipedia

   en.wikipedia.org/wiki/Buck_converter

   This circuit topology is used in computer motherboards to convert the 12 V DC power supply to a lower voltage (around 1 V), suitable for the CPU. Modern CPU power requirements can exceed 200 W, [10] can change very rapidly, and have very tight ripple requirements, less than 10 mV. Typical CPU power supplies found on mainstream motherboards use ...

3. Regenerative braking - Wikipedia

   en.wikipedia.org/wiki/Regenerative_braking

   Mechanism for regenerative brake on the roof of a Škoda Astra tram The S7/8 Stock on the London Underground can return around 20% of its energy usage to the power supply. [1] Regenerative braking is an energy recovery mechanism that slows down a moving vehicle or object by converting its kinetic energy or potential energy into a form that can ...

4. DC-to-DC converter - Wikipedia

   en.wikipedia.org/wiki/DC-to-DC_converter

   DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).

5. Chopper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Chopper_(electronics)

   0 to V volts: V to +∞ volts Position of chopper switch: In series with load: In parallel with load Expression for output voltage: VL dc = D × V volts: V o = V/(1 – D) volts External inductance: Not required: Required for boosting the output voltage Use: For motoring operation, for motor load: For regenerative braking for motor load. Type ...

6. Split-pi topology - Wikipedia

   en.wikipedia.org/wiki/Split-pi_topology

   The split-pi converter is a type of DC-to-DC converter that has an output voltage magnitude either greater than or less than the input voltage magnitude. It is a switched-mode power supply with a similar circuit configuration to a boost converter followed by a buck converter. Split-pi gets its name from the pi circuit due to the use of two pi ...

7. Power supply unit (computer) - Wikipedia

   en.wikipedia.org/wiki/Power_supply_unit_(computer)

   The +12 V supply was used for computer fan motors, disk drive motors and serial interfaces (which also used the −12 V supply). A further use of the 12 V came with the sound cards, using linear chip audio power amplifiers, sometimes filtered by a 9 V linear regulator on the card to cut the noise of the motors.
