摘要 |
<p>A pulsed power supply having a filter output and a battery backup includes electronic apparatus to sense when the AC source is failing. When the pulsed supply output has the same pulses as that which would be produced by the battery, the supply switches to battery backup mode. As the AC source returns, the supply switches to AC supply mode when the AC is at a level where the pulses produced by the supply would be the same as are actually being produced by the battery backup.</p> |
