초록정보

An integrated zero current switching(ZCS) quasi-resonant converter(QRC) for power factor correction and high efficiency with single switch is proposed in this thesis. Boost integrated circuit operating discontinuous conduction mode(DCM) and QRC are used for power factor correction and reducing switching loss, respectively. The design equations are obtained by deriving the large signal modeling of proposed circuit, then by using these equations, the power stage is composed. Also the control stage is designed by using the small signal modeling acquired from the large signal modeling. Thus a prototype converter has been designed and experimented. At rated condition, the THD in the input current waveform of this prototype has approximately 18%. The efficiency is obtained about 70%, the power factor is about 0.985 as well. Therefore, the proposed converter is suitable for a low power level converter with a switching frequency above several hundred kHz.
