Abstract :
This paper presents a novel integrated uninterruptible AC/DC power converter which operates at unity power factor. With the inherent high frequency triport configuration, it delivers uninterrupted DC power to the load through two independent power sources of commercial input power and battery power. The circuit operation and theoretical analysis, together with the experimental results from a prototype for verification of the theory, are presented
