ABSTRACT:
The present invention provides an uninterruptible switching power supply device and a method for uninterruptibly switching from AC input power to DC power, in which a high voltage circuit connected with the primary winding of the main transformer and a lower voltage circuit connected with a tap from the secondary are controlled by a PWM to operate synchronically. When the AC input is normal, the AC input power is transformed the main transformer to power a load. When the voltage of the AC input is lower than the predetermined value, the battery begins to discharge for compensating the power of the AC input. When the AC input is interrupted, the discharge of battery is transformed by the transformer in a self-coupling mode to power the load. The voltage transformation efficiency is improved with the device and method of the invention.
