Embodiment
As shown in Figure 2, the circuit of single-stage electromagnetic interface filter of the present invention has two inputs, two outputs and an earth terminal, and during use, shell should connect the earth.Circuit comprises common mode choke (also known as common mode inductance) L, filter capacitor C1 ~ C4.L is inoperative to series mode interference, but when there is common mode disturbances, because the flow direction of two coils is identical, after overcoupling, total inductance amount increases rapidly, therefore presents very large induction reactance to common-mode signal, makes it to not easily pass through, therefore is called common mode choke.Its two coils respectively around on the ferrite bead of low-loss, high permeability, when have electric current by time, the magnetic field on two coils will be strengthened mutually.The inductance value of L is relevant with the rated current I of electromagnetic interface filter, see table 1.
The relation of table 1. inductance value scope and rated current
| Rated current I (A) | 1 | 3 | 6 | 10 | 12 | 15 |
| Inductance value range L (mH) | 8~23 | 2~4 | 0.4~0.8 | 0.2~0.3 | 0.1~0.15 | 0.0~0.08 |
When rated current is larger, the wire diameter of common mode choke also wants corresponding increase, can bear larger electric current.In addition, suitably increase inductance value, low cut characteristic can be improved.C1 and C2 adopts film capacitor, and range of capacity is roughly 0.01 Μ f ~ 0.47 μ F, is mainly used to filtering series mode interference.C3 and C4 is connected across output, and by the neutral earthing of capacitor, effectively can suppress common mode disturbances.C3 and C4 also can be connected in parallel on input, still Ceramics electric capacity, and range of capacity is 2200Pf ~ 0.1 μ F.For reducing leakage current, capacitance must not more than 0.1 μ F, and capacitor midpoint should be connected with the earth.The withstand voltage of C1 ~ C4 is 630VDC or 250VAC.
L1, L2 of two-stage combined type electromagnetic interface filter, C3 and C4 be used for filtering common mode interference, C1, C2 and C5 filtering series mode interference.R1 is bleeder resistance, the charge discharging resisting of accumulation on C1, C2 and C5 can be fallen, avoid affecting filtering characteristic because of charge accumulated; The end of incoming cables of power supply can also be made after power-off not charged, and ensure the fail safe used, RF is fuse, the heater circuit of protection electro-heat equipment.Owing to adopting two-stage (also known as two joints) filtering, therefore the effect of filtering noise is better.
In the circuit of Fig. 1, L3 and C7 forms LC antiresonant circuit, and damping resistance R3 is connected in parallel on this circuit, effectively absorbs the higher harmonic component in rectifier transformer secondary loop, prevents output loop generation resonance, weakens the electromagnetic wave that electric energy turns heat energy generation.
Usually our AC supply voltage single line is connected with the earth, has the potential difference of 220V between another single line and the earth.People contacts and can produce electric shock.And the secondary of isolating transformer of the present invention is not connected with the earth, between its any two lines and the earth, there is no potential difference.People contacts any line and can not get an electric shock, so just safer.Secondly also have the output of isolating transformer to be that " open circuit " is isolated completely with input, so just the effective input to transformer (supply voltage that electrical network supplies) serves the effect of a good filtration.Thus provide pure supply voltage to power consumption equipment.
