High-voltage power supply circuit for fluorescent light

High-voltage power supply circuit for fluorescent light
The following figure shows a diagram of power fluorescent lights to a normal battery. It is very convenient when you can not use the grid. Principle of operation This scheme is a voltage converter for the type of blocking oscillator. Excitation it is because of feedback between the collector and base of the transistor circuits through respective windings of the transformer. Resistor R1 sets the mode of operation of the transistor. (more…)
