If the ignition coil is not linked to the ballast resistor, the ignition coil receives the entire supply voltage. The battery is usually utilized to power the ignition system. The battery voltage will most likely be 12V or 24V in most circumstances. If the voltage level decreased to 7-8V a...

Other appropriate base drive circuits for bipolar transistors may also be used. Although transistors 30 and 31 are bipolar transistors in the preferred embodiment, other semiconductor switches may be used, such as JFETs, MOSFETs, TRIACs etc. A starting resistor 36 couples a source of voltage ...
As illustrated, resistor 156 is connected with a first direct current (“DC”) power source 180, the output of the control unit 102 and resistor 158. Resistor 158 is further connected with diode 174, resistor 160 and capacitor 168. The first DC power source 180 is connected with capacitor ...
Ignition of the high pressure lamp will be as follows: Resistor R5 is the charging resistor for the capacitor C5, while resistor R6 is the charging resistor for capacitor C6. As the voltage increases on the capacitor C5, the voltage of the capacitor C6 will be reduced. When the voltage of...
The electronic ballast 102 comprises at least two resistors R8 and R10 arranged at least in a series connection relative to each other for measuring and/or regulating the currents of said at least two switching transistors Q1 and Q2, said resistor R8 being in connection with the switching ...
This paper presents a versatile ballast for discharge lamps, whose operation is based on the notion of a loss-free resistor (LFR). The ballast consists of two stages: (1) a boost converter operating in continuous conduction mode (CCM) and exhibiting an L
