Abstract
A power supply for generating an uninterruptible AC power signal. The power supply utilizes leakage inductance in its transformer to eliminate the need for an output inductor. In standby mode, the AC power signal is generated from a battery by a switching circuit. Certain components of the switching circuit are also used to charge the battery when the power supply is operating in line mode.
