摘要：

An investigation of a high-power piezoelectric transformer (PT) as a potential component for a fluorescent lamp (FL) ballast with power factor correction (PFC) is discussed. The attractiveness of the PT is primarily the simplicity of the resulting circuit, and it is easy to be produced in mass with a low cost. A single-stage charge-pump PFC ballast using a PT is proposed. The proposed ballast circuit improved the drawbacks of the conventional voltage-source charge-pump PFC (VS-CPPFC) scheme. Empirical PT modeling based on power level excitation is performed to design the proposed circuit, and the experimental and simulation results are provided to verify theoretical analysis.
