2. Switched-mode power supply - Wikipedia

   en.wikipedia.org/wiki/Switched-mode_power_supply

   In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. The switched-mode power supply's higher electrical efficiency is an important advantage. Switched-mode power supplies can also be substantially smaller and lighter than a linear supply because the transformer can be much smaller.

3. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   A modern computer power supply is a switch-mode power supply that converts AC power from the mains supply, to several DC voltages. Switch-mode supplies replaced linear supplies due to cost, weight, efficiency and size improvements. The diverse collection of output voltages also have widely varying current draw requirements.

4. Chopper (electronics) - Wikipedia

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

   The longer the switch is on compared to the off periods, the higher the total power supplied to the load. The PWM switching frequency has to be much higher than what would affect the load (the device that uses the power), which is to say that the resultant waveform perceived by the load must be as smooth as possible.

5. Power supply unit (computer) - Wikipedia

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

   A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.

6. Boost converter - Wikipedia

   en.wikipedia.org/wiki/Boost_converter

   For high efficiency, the switched-mode power supply (SMPS) switch must turn on and off quickly and have low losses. The advent of a commercial semiconductor switch in the 1950s represented a major milestone that made SMPSs such as the boost converter possible. The major DC to DC converters were developed in the early 1960s when semiconductor ...

7. Glossary of power electronics - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_power_electronics

   A mode of operation of stabilized power supplies in which all similar output terminals are connected together and arranged so that the total load is shared by all the supplies. phase control factor In the case of phase control , the ratio of the voltage at prevailing current delay angle to the voltage at zero current delay angle, all voltage ...

8. Power semiconductor device - Wikipedia

   en.wikipedia.org/wiki/Power_semiconductor_device

   A power semiconductor device is a semiconductor device used as a switch or rectifier in power electronics (for example in a switch-mode power supply).Such a device is also called a power device or, when used in an integrated circuit, a power IC.

9. Buck converter - Wikipedia

   en.wikipedia.org/wiki/Buck_converter

   Switch-Mode Power Supply Tutorial - Detailed article on DC-DC converters which gives a more formal and detailed analysis of the Buck including the effects of non-ideal switching (but, note that the diagram of the buck-boost converter fails to account for the inversion of the polarity of the voltage between input and output).
