Abstract
In recent years LED lighting has been exponentially growing. In daily life the demand for dimmable LED brightness has also increased. This requires that the conventional TRAIC dimmer is compatible with LED driver. This paper presents a low profile LED offline phase-cut dimming ballast, using the serial inductor half bridge (SIHB) converter with piezoelectric transformer (PT), which delivers at output 12W power and 1A current. It has competitive advantage in size compared to the current LED ballast on market with extra dimming capability.
