项目摘要
For small capacity rectifier circuits such as those for consumer electronics and appliances, capacitor input type rectifier circuits are generally used. Consequently, various harmonics generated within the power system become a serious problem. Various studies of this effect have been presented previously. However, most of these employ switching devices, such as FETs and the like. The absence of switching devices makes systems more tolerant to over-load, and brings low radio noise benefits. We propose a power factor correction scheme using a LC resonant in commercial frequency without switching devices. In this method, It makes a sinusoidal wave by widening conduction period using the current resonance in commercial frequency, Hence, the harmonic characteristics can be significantly improved, where the lower order harmonics, such as the fifth and seventh orders are much reduced. The results are confirmed by the theoretical and experimental implementations.In the second place, a novel diode bridge rectifier has been discussed, which is constructed solely from passive elements, and which has an almost sinusoidal input current waveform. Since it is not necessary to use switching devices, it eliminates switching losses and noises due to switching. In addition, since it is also unnecessary to employ a complicated driving circuit, so it is favorable in terms of cost performance. This circuit is most suitable for applications where there are relatively stable and constant loads. A disadvantage of this circuit is that a large alternating current flows through the capacitors in parallel to the diode. If we use electrolytic capacitors as the parallel capacitors, it is necessary to divide in parallel them and to select like recent low loss capacitors.
对于小容量整流电路,如消费电子和家用电器的整流电路,通常使用电容输入型整流电路。因此,电力系统内部产生的各种谐波成为一个严重的问题。关于这一效应的各种研究以前已经提出过。然而,这些中的大多数使用诸如FET等的开关器件。没有开关器件使系统对过载的容忍度更高,并带来了低无线电噪声的好处。提出了一种无开关器件的工频LC谐振器功率因数校正方案。该方法利用工频电流谐振,通过加宽导通周期形成正弦波,从而使系统的谐波特性得到显著改善,其中五次、七次等低次谐波得到了很大程度的降低。其次,讨论了一种新型的二极管桥式整流器,该整流器完全由无源元件构成,其输入电流波形接近正弦。由于不需要使用开关器件,因此消除了开关损耗和开关噪声。此外,由于也不需要使用复杂的驱动电路,因此在性价比方面是有利的。该电路最适合负载相对稳定和恒定的应用。这种电路的一个缺点是大量的交流电流经并联到二极管的电容器。如果我们使用电解电容器作为并联电容器,就必须将它们并联,并选择像最近的低损耗电容器。
