This paper presents a novel AC-side continuous-conduction-mode (CCM) voltage-source (VS) charge-pump (CP) power-factor-correction (PFC) self-oscillating full-bridge electronic ballast for fluorescent lamps. Unlike the conventional PFC electronic ballasts, the proposed AC-side CCM VS-CPPFC self-oscillating full-bridge electronic ballast has advantages of high power factor and low cost. The circuit analysis and the theoretical design criteria for the proposed AC-side CCM VS-CPPFC self-oscillating full-bridge electronic ballasts are presented. Finally, an 80W prototype circuit is built to validate the feasibility and performance of the proposed electronic ballast.
