2. Constant current - Wikipedia

   en.wikipedia.org/wiki/Constant_current

   An important usage of constant current power supplies is with LEDs. While a high series resistance is sufficient to light an LED, sometimes the design needs to guard against high current (or risk burning out the LEDs).

3. Constant power circuit - Wikipedia

   en.wikipedia.org/wiki/Constant_power_circuit

   The curve representing the power limit for the load for the range of current and voltage magnitudes in which the load circuit may safely operate Battery chargers are the largest single application for current controlled power supplies requiring either constant-current or constant-power output characteristics.

4. Power supply - Wikipedia

   en.wikipedia.org/wiki/Power_supply

   A power supply is an electrical device that supplies electric power to an electrical load. The main purpose of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. As a result, power supplies are sometimes referred to as electric power converters. Some power supplies are ...

5. Load regulation - Wikipedia

   en.wikipedia.org/wiki/Load_regulation

   Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

6. Current source - Wikipedia

   en.wikipedia.org/wiki/Current_source

   Conversely, a current source provides a constant current, as long as the impedance of the load is sufficiently lower than the current source's parallel impedance (which is preferably very high and ideally infinite). In the case of transistor current sources, impedances of a few megohms (at low frequencies) are typical. Because power is current ...

7. Glossary of power electronics - Wikipedia

   en.wikipedia.org/wiki/Glossary_of_power_electronics

   A stabilized power supply that operates as a constant voltage power supply or constant current power supply depending on load conditions. constant voltage to constant current crossover The behavior of a stabilized power supply that automatically converts the mode of operation from voltage stabilization to current stabilization when the output ...
