Introduce the function of circuit each several part below in detail:
1, electromagnetic interference (EMI) filter
The technical measures that suppress EMI have shielding, ground connection (floating ground, single-point ground and ground network) and filtering.Wherein, filtering technique is to suppress the effective and the most most economical means of conducted interference.Because various interference are the most serious at the system interface place, so electromagnetic interface filter is placed on the porch of system power supply line.The conducted interference of AC power cord comprises differential mode noise composition and common-mode noise composition.In order to play the effect that suppresses to disturb, reduce noise, adopt the alternating current circuit electromagnetic interface filter.Electromagnetic interface filter had both suppressed common mode and differential mode interference from electrical network, guaranteed that common-mode noise and differential mode noise do not appear in secondary side.Simultaneously, it also plays attenuation to the electromagnetic interference that electric ballast self produces, and is not contaminated to guarantee electrical network.
