Abstract :
This paper presents a family of the piezoelectric-transformer (PT)-based bridgeless continuous-conduction-mode (CCM) charge-pump (CP) power-factor-correction (PFC) electronic ballasts for a 32-W 4-ft linear fluorescent lamp, including the voltage-source (VS) type, current-source (CS) type, and VS-CS (VSCS) type. By replacing the LC resonant tank and high-voltage transformers in discrete CCM VS, CS, and VSCS CP-PFC electronic ballasts with PTs, the cost and volume can be reduced. The experimental results compare the presented electronic ballasts according to the performance of power factor, total harmonic distortion, crest factor, dc-bus voltage stress, and efficiency.
