In doing so, film capacitors can be adopted instead of electrolytic capacitors to achieve a long power supplies lifetime. The voltage ripple of the storage capacitor is intentionally increased to reduce the storage capacitance. The method of determining the storage capacitance for ensuring that the boost power factor correction converter operates normally in the whole input voltage range is also discussed. For the purpose of further reducing the storage capacitance, a method of injecting the third harmonic current into the input current flow is proposed. While ensuring that the input power factor is always higher than 0.9 to comply with regulation standards such as ENERGY STAR, the storage capacitance can be reduced to 65.6% of that with an input power factor of 1.

The power supply for LED lighting is an ac/dc converter, which converts a regular ac voltage to a low dc voltage for an LED driver. The input power factor is an important requirement of the ac/dc converter. It needs to be higher than 0.9 for most commercial luminaries 5. Thus, the ac/dc converter must typically have the function of power factor correction (PFC). In a PFC converter, the input current is forced to be in phase with the input voltage, leading to a pulsating input power, while the output power is constant. To achieve this, a storage capacitor with large capacitance is required for balancing the instantaneous power difference. Due to the high capacity required for capacitance, an electrolytic capacitor is often used as the storage capacitor. However, it is well known that because of its liquid electrolyte, the lifetime of an electrolytic capacitor is quite limited with only several thousand hours under rated operating conditions. Even with a conservative design, the theoretical lifetime of electrolytic capacitors is only about 3 000 h (at a high operating LEDs temperature) 6. This is much shorter than the potential lifetime of LEDs (50 000 h). Thus, the electrolytic capacitor is an obstacle to the overall long-term reliability of the LED and its power supply.,論文題目 作者 摘要 關(guān)鍵詞 正文 結(jié)論 致謝 參考文獻(xiàn) 作者簡(jiǎn)介,引言,LED的優(yōu)點(diǎn),LED電源需要 功率因數(shù)校正(PFC)功能,PFC變換器需要很大的儲(chǔ)能電容,儲(chǔ)能電容壽命較短， 與LED的長(zhǎng)壽命不相匹配,2019/7/16,16,A review of literature shows that a variety of LED power supplies and driver solutions, which can accurately control the current of the LED while achieving a near-unity input power factor, have been proposed 710. However, an electrolytic capacitor is required in these applications. PFC converters can be classified into two types: two-stage and single-stage. Two-stage PFC converters consist of a PFC stage and a dc/dc stage. They have been widely applied in adaptors for laptops and silver box 1114. Single-stage PFC converters integrate the PFC stage and the dc/dc stage, leading to simple topology and low cost. They are suitable for low-power applications 1518. Unfortunately, no effective method has been proposed to significantly reduce the storage capacitance in a PFC converter such that a long lifetime of a converter can be achieved.,論文題目 作者 摘要 關(guān)鍵詞 正文 結(jié)論 致謝 參考文獻(xiàn) 作者簡(jiǎn)介,引言,PFC變換器的研究綜述， 指出這些方案都不能減小儲(chǔ)能電容,2019/7/16,17,論文題目 作者 摘要 關(guān)鍵詞 正文 結(jié)論 致謝 參考文獻(xiàn) 作者簡(jiǎn)介,正文主體部分,闡述所提出方法 相關(guān)理論分析 仿真和實(shí)驗(yàn)驗(yàn)證,II.

In a two-stage PFC converter, a storage capacitor is used to balance the pulsating input power and the dc constant output power. To significantly reduce the storage capacitor, the voltage ripple of the storage capacitor can be intentionally increased. However, a very large voltage ripple can result in the unstable operation of the boost PFC converter and a very high voltage stress on the power switches. This paper gives the derivation of the relationship between the voltage ripple and the value of the storage capacitor, and proposes a guideline for the selection of a suitable value for the storage capacitor. Moreover, a method of injecting the third harmonic current into the input current flow is proposed to reduce the pulsation of the input power. This can further reduce the storage capacitance. While keeping the input power factor at 0.9 to comply with the requirement of ENERGY STAR, the storage capacitor can be reduced to 65.6% of that with an input power factor of 1.
