| 摘要 |
A power converter circuit designed to provide an uninterruptible source of power to electrical and electronic apparatus such as computers, including an input (1) connected to a source of AC, first circuitry (2) converting said AC into DC (3) without transformation, second circuitry (4) adapted to convert said DC into a second DC voltage (5) which may be adapted to supply a load (8) and may charge a battery (6). The DC voltage is controlled by a regulator controller (9) on the basis of a feedback signal dependent upon this voltage and the current flowing into the battery. When the source AC is available the voltage supplies the battery and load, while if no source AC is available the load is supplied by battery. |
