| 摘要 |
<p>A DC power supply includes a magnetic amplifier (18), filter, back-up battery (24), switch-over regulating circuit (22) and error amplifier (21). The magnetic amplifier (18) receives AC pulses and controls the pulse width of the pulses. The filter converts the pulses to a DC output. The switch-over regulating circuit (22) connects the battery (24) to the DC output. The error amplifier (21) monitors the DC output and provides, at its output, an error signal to the magnetic amplifier (18) and the switch-over regulating circuit (22).</p> |
