发明名称 UNINTERRUPTIBLE DC POWER SOURCE EQUIPMENT
摘要 PURPOSE:To reduce power loss and the size of equipment by separating a power supply path from a rectifier to a load and a power supply path from a battery to the load each other and arranging a voltage regulation switcher in the latter path. CONSTITUTION:Upon application of AC voltage onto a terminal. 11, current I1 flows through a rectifier 1 to a load 3 under normal operating condition. At the same time. charge current flows through a recharger 20 to a battery 4 thus recharging the battery 4. Upon interruption or voltage drop of an AC power source, a voltage regulation switcher 21 functions to feed voltage stably from the battery 4 to the load 3 thus supplying DC current to the load 3. Since there is no voltage regulator such as dropper circuit between the rectifier 1 and the load 3, power can be fed from the rectifier 1 to the load 3 with low loss.
