Electronic ballast system

摘要: An electronic ballast system includes a first capacitor (C 2 ) electrically coupled to the filament (30) of gas discharge tube (12) and becomes power supply subsequent both its charging discharging operations. The collector (38) transistor (Tr) is connected ). primary winding (22) in parallel relation. transformer (t) secondry (24) which on opposing ends thereof feedback relation base (44) emitter (42) (Tr). Pulses current polarity (122 124) generated through secondary alternately provide conducting non-conducting states for charge source operation (12). combination provides voltage limiting preventing kick back from exceed safe operating limit allows use energy produce visible light output instead heat.
