Based on the digital signal processer of TMS320 F28335 and the complex programmable logic device that EPM7256 AETC100, a novel digital control scheme for an on-line high frequency uninterruptible power system（UPS）, which consists of an active power factor correction unit, a battery charging and discharging unit, an inverter, a control unit, an auxiliary power supply and a human-machine interface, is designed in this paper. Firstly, the structure and work principle of this UPS are described. Then, the key digital control technologies such as the dual half-wave power factor correction（PFC）, the double-loop control strategy using proportional-resonant（PR） regulator for the inverter, the decoupled double synchronous reference frame phase-locked loop（DDSRF-PLL） are discussed detailedly. Finally, a series of experiments are conducted, and the results verify that the proposed scheme has high feasibility and reliability.
