Stabilized power supply

...The main characteristics are expressed by voltage, frequency, number of phases, and maximum load power, but there are also special power supplies such as the following. A constant current source is a power supply that supplies a nearly constant current, whereas a normal power supply has a voltage close to a constant value. A stabilized power supply is a power supply device that is controlled so that the load voltage hardly changes in response to changes in the load current or input voltage within the normal range. An uninterruptible power supply is a power supply device that continues to supply power to the load continuously using built-in batteries, even if the regular power supply from the power company or other source is interrupted. An emergency power supply is a power supply device prepared for disasters, power outages, etc., and is often an engine generator. ...

…電圧，周波数，相数，最大負荷電力などで主要な性質を表現するが，特殊な電源装置には以下のようなものもある。定電流源はふつうの電源が，電圧が一定値に近いのに対し，ほぼ一定の電流を供給する電源，安定化電源は通常の範囲の負荷電流の変化や入力電圧の変化に対し，負荷の電圧などがほとんど変化しないように制御された電源装置，無停電電源は電力会社などの常用電源が停電しても，内蔵の電池などを用いて負荷には連続的に電力を供給し続ける電源装置である。非常用電源は災害，停電などに備えるための電源装置で，エンジン発電機が多い。…
