Embodiment Construction

[0024] The working principle of the filter correction filter system of the present invention is as follows. It is connected between a power line and a neutral wire, generally in the manner shown in Figure 2, and only comes into play when interference is present. This system mainly has the following three functions:

[0025] 1. It can detect the rising instantaneous voltage and when it exceeds the peak value of the voltage by more than 10%, it will limit and absorb the excess part. For example, when the specified voltage is 120 volts (effective value), and the peak voltage reaches plus or minus 190 volts, the system starts to work.

[0026] 2. When a momentary high voltage is generated, it will reduce its rise time. So the momentary high voltage will "slide" into the isolation level. Doing so prevents another switching event from causing further ringing.

[0027] 3. It will absorb all high damping oscillation interference at a rate of 6db per group of 10 above 60 Hz.

Abstract

The waveform correction filter connected on the A.C. power line for absorbing and removing various mains pollutions includes a fuse and a coaxial non-crystal ring inductor connected between power line and neutral line and a low pass filter series-connected with fuse and waxial non-crystal ring inductor. It filter includes a capacitor, a non-linear resistor parallel-connected with said capacitor, a magnetic core inductor and a resistor which are mutually series-connected and parallelly-connected with the above-mentioned non-linear resistor and capacitor, and a lamp which can be series-connected with above-mentioned resistor and magnetic core inductor or bridge-connected on the resistor.

Description

Background of the invention [0001] For many years, those who monitor large amounts of AC power have been concerned about the quality of these power sources. Most of the newer equipment in use today is very sensitive to transient voltages such as pulse spikes, power surges, and random radio frequency noise; but at the same time, these devices may also generate their own transient voltages and will The transient voltage is injected back into the power line. When a switch is turned on or off, an echoing pulse is created in the power line. The pulses generated by motor starting and stopping are generally called surges. [0002] In addition to the random occurrence of radio frequency pollution, various electric motors may generate wave frequencies. All this power pollution reduces the efficiency of motors, generators and transformers. The waveform of the electric power applied to these devices is distorted, so that eddy currents are generated in the ferrous metal parts of these...
