Intro:
What is EnerSolÂŪ Plates?
Why we need EnerSolÂŪ Plates?
In power conversion: change from linear to switch-mode supplies (high switching frequency, noise (harmonics)) and increase of switching frequencies. Together with the increasing use of electronics this leads to a general EMC degradation and consequently EMC legislation is becoming stricter world-wide.
Of course, the first step to avoid interference problems is a good design practice, to tackle the problem right from the start. This can be insufficient if the interference is directly related to the inherent operating principle and too late if the interference is detected not earlier than in the final design phase. In such cases extra suppression components are necessary, like EnerSolÂŪ Plates.
EnerSol Inc. Tokyo, Japan 21-Nov-19 2 EnerSolÂŪ Plates provide a solution to many problems of conducted and (indirectly) radiated interference. They can be applied almost anywhere:
By being installed on wire or cable, even if the cables are shielded.
No ground connections are necessary as EnerSolÂŪ Plates are connected in series with the interfering circuit and not in parallel as in the case of other filters. The wideband, lossy impedance makes EnerSolÂŪ Plates well-suited as RF suppressor
General principles of EMC
Regulations
Historically, all EMI regulations stated emission limits only. These define the maximum level of interference allowed as a function of frequency. In case of conducted interference, it applies to the voltage on all inputs and outputs of the equipment, in case of radiated interference it applies to the field strength at a certain distance.
Suppression with EnerSolÂŪ Plates
The decibel (dB) as a unit is practical because interference levels are also expressed in dB. However, insertion loss depends on source and load impedance, so it is not a pure product parameter like impedance (Z). In the application, source and load impedance generally are not 50 âĶ resistive. They might be reactive, frequency dependent and quite different from 50 âĶ.
Insertion loss is a standardized parameter for comparison, but it will not predict directly the attenuation in the application.
At low frequency, an EnerSolÂŪ Plate is a low-loss, constant self-inductance. Interferences occur at elevated frequencies and there the picture changes. Losses start to increase and at a certain frequency, the product resonant frequency, permeability drops rapidly, and the impedance becomes almost completely resistive. At higher frequencies it even behaves like a lossy capacitor.
While for most applications the operating frequency should stay well below this resonance, effective interference suppression is achieved up to much higher frequencies.
The impedance peaks at the resonant frequency and the EnerSolÂŪ Plate is effective in a wide frequency band around it. The material choice follows from the critical interference frequencies; ideally, they will coincide with the product resonance frequency, the top of the impedance curve. According to Snoekâs law, this resonant frequency is inversely proportional to the initial permeability, which gives us a guide for material choice. The whole RF spectrum can be covered with EnerSolÂŪ
Plates.
Preferred applications of EnerSolÂŪ Plates:
Mainly
Some other cases
Also, those applications where both high operating temperatures (140šC) and high currents are involved e.g. power lines in industrial, but especially automotive environments. Suppressing of interference signals along these lines can be achieved by inserting EnerSolÂŪ Energy Saving + Plates.
Basic Characteristics of EnerSolÂŪ Compared to Inductors &
Noise Countermeasures Using Them
Dealing with Noise Using Inductors:
Because EnerSolÂŪ Plates convert noise into heat in addition to shunting noise away, they can be expected to provide excellent noise elimination performance.
So, as a conclusion at this stage we can say that the noise attenuation plate (EnerSolÂŪ) has a power reduction effect when installed at the breaker closest to the load. By cleaning the sine wave from EMI noise as the paper shows which will improve the sine wave and help reducing the consumed energy.
More tests and investigations to be conducted are to clarify the estimated amount of savings.
