A 40 watt fluorescent tube lamp or two 20-watt tubes in series will be driven by this circuit but this circuit will produce less brightness than usual, since this circuit only deliver 6-12 Watts. This circuit draws 0.9-1.2 Amps for 2 x 20 watt tubes, or 0.45-0.9A for 1 x 20 watt tube, depending on the potentiometer setting. Here is […]
Read moreA 40 watt fluorescent (tube lamp, TL) or two 20-watt tubes in series will be driven by this circuit. The transformer is wound on a ferrite rod 10mm dia and 8cm long. The diameters of the wire are not critical but our prototype used 0.61mm wire for the primary and 0.28mm wire for the secondary and feedback winding. When circuit […]

This is example of a simple inverter that can be used to power fluorescent lamp and a small strobe. This circuit will produce over 400VDC from a 12 VDC, 2.5 A power supply or marine battery or an auto. This circuit is very simple because it does not require custom transformers or coils. Also all components are readily available. Here […]

This is a simple high voltage inverter circuit. It is uses NPN transistor type 2N3055. This circuit used to invert low voltage to high voltage. Besides that, this circuit uses flyback transformer that can obtained from B/W or color TV or computer monitor. R1 (110 Ohm/5W) and R2 (27 Ohm/5W) are used to limit the current so as to reduce […]
