Design of fluorescent lamp ballast with PFC using a power piezoelectric transformer

An investigation of a high power piezoelectric transformer as a potential component for a fluorescent lamp ballast with power factor correction (PFC) is discussed. The attractiveness of the piezoelectric transformer is primarily the simplicity of the resulting circuit, and it is easy to produce in mass with a low cost. Electrical modeling, considering operating current level and analysis of the piezoelectric transformer are performed through measurements to design a fluorescent lamp ballast with a single stage charge pump PFC. The experimental and simulation results are provided to verify theoretical analysis.
