Abstract
This paper presents a portable power supply equipped with a battery charger. The proposed system can be operated separatedly distinguishing between DC/AC and AC/DC function. The former uses a battery and the latter a line voltage as the power source to operate on an inverter and a battery charger, respectively. To keep the output voltage being sinusoidal and to have the high dynamic performances even In the cases of load variations, a proper control method is adapted. The operational principles and analysis are explained in detail. The validity of the proposed system is proved from the experimental results.
