还有一篇关于音频动态范围压缩的相关珍贵论文，这是一个很实用但是又很少有人关注的领域，希望对大家有帮助！(Have an audio dynamic range compression on the relevance of valuable papers, it is a very pragmatic but also very few areas of concern, and they hope to have everyone help!)

这是浙江金融职业学院，金融专业2010届论文题目汇总(This is the Zhejiang Financial Professional College, the financial professional summary of the 2010 Session Topic)

In higher power applications to utilize the full line power and reduce line current harmonics PFC Pre-regulators are generally required. In these high power applications interleaving PFC stages can reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall magnetic volume and filter capacitor volume increasing the converters overall power density. This is made possible through distributing the power over two interleaved boost converters and the inductor ripple current cancellation that occurs with interleaving, reference [5]. This application note will review the design of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T

本压缩包 包含 任务书、论文以及答辩ppt，虽说是课程设计，但是按照毕业设计书写，内容充实 本次课程设计主要是对象湖变的电网进行保护整定，对d1至d6共6个地方进行了最大方式与最小方式运行情况下的短路电流计算。计算完短路电流后，对L1至L5共5条线路进行电流保护整定。但是由于线路较短，线路阻抗较小。经计算后均不适合三段式电流保护。所以采取了纵联差动保护作为主保护，定时限过电流保护作为后备保护。对于变压器，采用纵联差动保护与气体保护共同作为主保护，过负荷保护作为后备保护。(The curriculum design is the object variable grid lake protection setting of D1 to D6, 6 places for the maximum and minimum operation mode under the condition of short-circuit current calculation. Calculation of short-circuit current after the end, L1 to L5 a total of 5 lines of current protection setting. But because of shorter lines, line impedance is small. The calculations are not suitable for three phase current protection. So take a longitudinal differential protection as the main protection, timing and limiting current protection as a back-up protection. For transformers, using longitudinal differential protection and gas protection as the main protection, overload protection as a back-up protection.)
