| Zusammenfassung: | To reduce cost while properly dealing with start-up currents from a load in a system that starts up the load by switching to an emergency generator when no power is fed from a power-supply.SOLUTION: A power-supply device comprises: a power-supply bus bar; a generator for feeding power to an AC motor; a storage battery for charging part of the power fed from an external power-supply; a charging/discharging switching part for switching charging/discharging of the storage battery; and a charging/discharging control part for controlling an operation of the charging/discharging switching part. The charging/discharging control part that makes the charging/discharging switching part be in a charging state during a steady operation switches the charging/discharging switching part from a charging state to a discharging state to feed the power charged in the AC motor when operating a damper in an emergency operation in which no power can be fed from the external power-supply.SELECTED DRAWING: Figure 3
【課題】電源からの電力供給が得られなくなった場合に非常用の発電機に切り換えて負荷を起動するシステムにおいて、負荷の起動電流に対応しつつ、コストを低減させる。【解決手段】電源母線と、交流モータに電力を供給するための発電機と、外部電源から供給された電力の一部を充電するための蓄電池と、蓄電池の充放電を切り換えるための充放電切換部と、充放電切換部の動作を制御する充放電制御部とを備え、充放電制御部は、定常動作において充放電切換部を充電状態にさせ、外部電源から電力が供給できなくなった非常動作においてダンパを動作させる場合に、充放電切換部を充電状態から放電状態に切り換えて交流モータに充電した電力を供給させる、電源装置。【選択図】図３ |
