Inverter Fluorescent Lamp Schematic 40w

This 40W fluorescent lamp inverter allows you to run 40W fluorescent tubes from any 12V source capable of delivering 3A. This is basically a larger version of the 12VDC Fluorescent Lamp Driver and can be used to light regular or blacklight tubes.

MISC Wire, Case, Board, Heatsink For Q1, heatshrink, AM antenna rod for coil

Notes

# Email Bart Milnes (the.milnes@xtra.co.nz) with questions, comments, etc.

# Wind L1/T1. You will need an AM antenna rod that is about 60mm (2.5 inches) long to wind T1/L1 on. T1/L1 are wound on the same core. Shrink a layer of heatshrink over the core to insulate it. Leave 50mm of wire at each end of the coils. Primary: Wind 60 turns of 1mm diameter enamelled copper wire on the first layer and put a layer of heatshrink over it. Feedback: Wind 13 turns of 0.4mm enamelled copper wire on the core and then heatshrink over that. Secondary: This coil has 450 turns of 0.4mm enamelled copper wire in three layers. Wind one layer and then heatshrink over it. Do the same for the next two. Transformer/Inductor Winding

# Calibrate/test the circuit. To calibrate/set up the circuit connect the 2.2 Ohm 1W resistor (R3) in series with the positive supply. Connect a 40W fluorescent tube to the high voltage ends of the transformer. Momentarily connect power. If the tube doesn't light immediately reverse the connections of L1. If the tube still doesn't work, check all connections. When you get the tube to light remove the 2.2 ohm resistor and the circuit is ready for use. You will not need R3 again.

# This circuit is designed for 220V lamps. It will work with 120V units just fine, but will shorten the life of the tube.

500W Low Cost Inverter Circuit 12V to 220V

Using this ambit you can catechumen the 12V dc in to the 220V Ac. In this ambit 4047 is use to accomplish the aboveboard beachcomber of 50hz and amplify the accepted and again amplify the voltage by application the footfall transformer. How to account agent rating

The basal blueprint is P=VI and amid ascribe achievement of the agent we accept Power ascribe = Power output

For archetype if we appetite a 220W achievement at 220V again we charge 1A at the output. Again at the ascribe we charge accept at atomic 18.3V at 12V because: 12V*18.3 = 220v*1

So you accept to wind the footfall up agent 12v to 220v but ascribe ambagious charge be able to buck 20A.

12V to 120V Inverter Circuit Diagram

# Q1 and Q2, as able-bodied as T1, actuate how abundant wattage the inverter can supply. With Q1,Q2=2N3055 and T1= 15 A, the inverter can accumulation about 300 watts. Larger transformers and added able transistors can be commissioned for T1, Q1 and Q2 for added power.

# The easiest and atomic big-ticket way to get a ample T1 is to re-wind an old bake transformer. These transformers are rated at about 1KW and are perfect. Go to a bounded TV adjustment boutique and dig through the dumpster until you get the better bake you can find. The bigger the bake the bigger transformer. Abolish the transformer, actuality accurate not to blow the ample aerial voltage capacitor that ability still be charged. If you want, you can analysis the transformer, but they are usually still good. Now, abolish the old 2000 V secondary, actuality accurate not to accident the primary. Leave the primary in tact. Now, wind on 12 turns of wire, aberration a bend (center tap), and wind on 12 added turns. The guage of the wire will depend on how abundant accepted you plan to accept the agent supply. Enamel covered allurement wire works abundant for this. Now defended the windings with tape. Thats all there is to it. Remember to use aerial accepted transistors for Q1 and Q2. The 2N3055's in the genitalia account can alone handle 15 amps each.

# Remember, back operating at aerial wattages, this ambit draws huge amounts of current. Don't let your array go asleep :-).

# Since this activity produces 120 VAC, you charge accommodate a agglutinate and body the activity in a case.

# You charge use tantalum capacitors for C1 and C2. Regular electrolytics will overheat and explode. And yes, 68uF is the actual value. There are no substitutions.

# This ambit can be catchy to get going. Differences in transformers, transistors, genitalia substitutions or annihilation abroad not on this folio may account it to not function.

# If you appetite to accomplish 220/240 VAC instead of 120 VAC, you charge a agent with a 220/240 primary (used as the accessory in this ambit as the agent is backwards) instead of the 120V assemblage defined here. The blow of the ambit stays the same. But it takes alert the accepted at 12V to aftermath 240V as it does 120V.

# Check out this appointment affair to acknowledgment abounding of the best frequently asked questions about this circuit: 12 - 120V Inverter Again. It covers the best accepted problems encountered and has some accessible suggestions.

Here The Part List Of 12V to 120V Inverter Circuit Diagram :
