Abstract

This paper proposes a bridgeless-type ac-side continuous-conduction-mode (CCM) current-source (CS) charge-pump (CP) power-factor-correction (PFC) electronic ballast. The drawbacks of conventional dc-side discontinuous-conduction-mode (DCM) electronic ballasts include high di/dt, high current stress, and high switching losses. As a result, conventional dc-side DCM CS-CP-PFC electronic ballasts have low efficiency, due to the DCM operation, and the ballasts require a large input electromagnetic interference filter. Conventional dc-side CCM CS-CP-PFC electronic ballasts are able to solve these problems, but still require a higher component count. To efficiently reduce the cost of electronic components, a bridgeless-type ac-side CCM CS-CP-PFC electronic ballast is proposed. A 32-W rated power electronic ballast prototype circuit is designed and implemented. Experimental results verify that the input-current harmonics meet the IEC 61000-3-2 Class-C Standard, and the CP capacitor helps the PFC inductor current to achieve CCM and high power factor
