AC-DC switching regulator to supply uninterruptible power |
摘要 |
An uninterruptible power supply utilizes a switching circuit which under normal operation modulates at a high frequency a signal provided by a commercial AC line to control the energy flow through a transformer between an input accepting the AC line source and a rectified DC output. The switching circuit which performs the modulation is optimally arranged to be coupled to a reserve energy source such as a charge storage capacitor or battery. It operates upon failure of the AC signal input to provide energy from the reserve source to the load by operating as a switching regulator.
