含各次滤波器的TSC动态无功功率补偿装置;6%电抗的TSC动态无功功率补偿装置固定投入各次滤波器的装置，由于有源滤波器技术和价格的原因，目前还难在国内推广。

在保养的同时要仔细检查变频器，定期送电，带电机工作在2hz的低频约10分钟，以确保变频器工作正常。

近年来，发展起来的一些新型器件将改变这一现状，如IGBT、IGCT、SGCT等等。由它们构成的高压变频器，性能，可以实现PWM逆变，甚至是PWM整流。不仅具有谐波小，功率因数也有很大程度的提高。

要解决这些问题，选择模拟方式大的好处是可以分析提高触摸屏的分辨率，但是抗千扰能力比不上脉冲方式;选择脉冲方式虽然抗干扰能力强，但是存在脉冲方式在接收方需要一个响应过程时间的问题，而触摸屏却要求极快的速度，因此要在自适应电路、单片机软件、模具设计、透光材料选择等几个方面要有技术突破

TSC dynamic reactive power compensation device with various filters; The 6% reactance TSC dynamic reactive power compensation device is fixed into each filter device, because of the active filter technology and price, it is difficult to popularize in China.

At the same time of maintenance, it is necessary to carefully check the inverter, regularly send power, and work with the motor at the low frequency of 2hz for about 10 minutes to ensure that the inverter works normally.

In recent years, some new devices have been developed that will change this situation, such as IGBT, IGCT, SGCT and so on. The high voltage frequency converter composed of them can realize PWM inverter and even PWM rectification. Not only the harmonics are small, but also the power factor is greatly improved.

To solve these problems, the biggest advantage of choosing the analog mode is that the resolution of the touch screen can be analyzed and improved, but the anti-interference ability is not as good as the pulse mode; Although the selection of pulse mode has strong anti-interference ability, there is a problem that the pulse mode requires a response process time on the receiver, and the touch screen requires extremely fast speed, so there should be technical breakthroughs in several aspects such as adaptive circuit, microcontroller software, mold design, and selection of light-transmitting materials
