POWER FACTOR CONTROL DEVICE AND METHOD THEREFOR |
| 摘要 |
<p>A power factor correction device (26,75) stores the output of an error amplifier (32) on a storage element (39). A zero crossing detector (37) detects the zero crossings of the AC input voltage and enables the power factor correction device (26,75) to adjust the value of the voltage stored on the storage element (39).</p> |
