在特殊情况下，例如在薄弱电网（低短路容量）和 高 谐波 功 率负载（例如直流驱动或滑雪缆车系统），或者电力部门或对THD-U有特别要求的重要生产工序（即 THD-U的值要求特别低），即需要一种“清洁”的电流（例如计算机中心，半导体行业，具有较长工序链的生产过程），这些场合下，就需要更好的减少网络中 的 谐波 震 荡 ，而常规的失谐设备就往往达不到要求。 janitza.de | In special cases such as in weak (low [...] short-circuit power) [...] networks with simultaneously high harmonic loads (e.g. DC drives or ski lifts) or in cases where the energy supply companies or critical production processes require low THD-U values, which means that a “clean” electricity quality is required (e.g. research centres, semiconductor industries, long process chains...), it may be necessary to achieve more harmonic reductions than standard [...]de-tuned systems can manage. janitza.com |
所以，一般音箱高音损失的功率比低音喇叭低得多，以求高低音平衡；而功放好比一个电流调制器，它的输入音频信号的控制下，输出大小不同的电流给音箱，使之发生大小不同的声音，在一定阻抗条件下，要想让标称功率为200W的功放达到400W或几倍的输出其实很容易，只是功放的失真（THD）将会大大地增加，这种失真主要产生在中、低频信号中的高 频 谐波 ， 其失真越大，高 频 谐波 能 量就越大，而这些高频失真信号都将随高频音乐信号一同进入高音头，这就是为什么小功率功放推大音箱会发生烧高音头的原因。 seeraudio.com | Therefore, a general speaker tweeter power loss is much lower than the bass horn, in order to high bass balance; while the amplifier is a current modulator, the input audio signal under the control of different sizes, the output current to the speaker, the size of different voices, the impedance condition, want to let the nominal power 200W amplifier to 400W or several times the output is actually very easy, just amplifier distortion ( THD ) will greatly increase, this distortion is mainly produced in the medium, low frequency signal in high frequency harmonic distortion, which is greater, the high frequency harmonic energy is bigger, and these high frequency distortion of the signal will be with the music signal of high frequency to enter the high head, which is why the small amplifier on the great speaker would burned treble head of. seeraudio.com |
