Temperature changes will cause the BS value change u, H, HC; the changes will lead to changes in the value of BS CFLs line of work status; BS value increased transistor drive current will cause the resulting reduced. Therefore, in the 110V line, if you choose to use the BS values ??at high temperatures change relatively large ring, it will lead to light at high temperatures, turn off and then immediately open Tangxia magnetic connectors, lamp will not start; across the lamp filament redness houjie ring connector because the lamp does not start; power would be twice the rated power. In addition, because the lamp does not start, the two ends of the filament temperature will rise very high (nearly 300 ℃ above) and this will burn the plastic parts. Choose turns the whole bundle cable through a ferrite bead constitutes a common mode choke, if necessary, can also be in the ring on top of the cable around a few turns. The more turns, the lower frequency interference suppression effect, the better, but at higher frequencies the noise weak inhibition. In practical engineering, according to the frequency characteristics of the interference current ring to adjust the number of turns. Usually when a wide-band interference signals, you can set both on the cable ring, each magnetic surround different turns, which can interfere with high frequency and low frequency while suppressing interference. From the mechanism of action of the common mode choke point of view, the greater the impedance, the more obvious effects of interference suppression. The common mode choke coil impedance from the common mode inductance Lcm = jwLcm Nan magnetic connector, from the formula is not difficult to see that, for a certain frequency noise, magnetic inductance bigger the better. But the reality is not the case, because there is an actual ring parasitic capacitance, and its existence is parallel with the inductor. When confronted with a high-frequency magnetic interference signal connectors, capacitors capacitance is small, the magnetic inductance short circuit, so that the common mode choke useless.
