12V DC to 120-230V DC with IC 555 Inverter

This DC-to-AC inverter schematic produces an AC output at line frequency and voltage. The 555 is configured as a low-frequency oscillator, tunable over the frequency range of 50 to 60 Hz by Frequency potentiometer R4. Parts List: R1 = 10K R2 = 100K R3 = 100 ohm R4 = 50K potmeter, Linear C1,C2 = 0.1uF C3 = 0.01uF C4 = 2700uF Q1 = TIP41A, NPN, or equivalent Q2 = TIP42A, PNP, or equivalent L1 = 1uH T1 = Filament transformer, your choice The 555...

be Inverter 12 V DC to 120 V AC

This Inverter takes 12 volt d.c and steps it up to 120 volt a.c. The wattage depends on which transistors you use for Q1 and Q2, as well as the "Amp Rating" of the transformer you use for T1. This inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts. If Q1, Q2 are 2N3055 NPN Transistors and T1 is a 15 A transformer, then the inverter will supply about 300 watts. Larger transformers and more powerful transistors can be...

great 100 Watt Inverter 12V DC to 220V AC

Electronic schematic diagram for 100 Watt Inverter 12V DC to 220V AC. The IC1 Cd4047 wired as an astable multivibrator produces two 180 degree out of phase 1/50 Hz pulse trains.These pulse trains are are preamplifes by the two TIP122 transistors. The out puts of the TIP 122 transistors are amplified by four 2N 3055 transistors (two transistors for each half cycle) to drive the inverter transformer. The 220V AC will be available at the secondary...

some 500W Inverter 12V DC to 220V AC

This is inexpensive inverter circuit which able to convert 12V DC become 220V AC. IC CD4047 is use to generate the square wave of 50hz and amplify the current and then amplify the voltage by using the step transformer. How to calculate transformer rating The basic formula is P=VI and between input output of the transformer we have Power input = Power output For example if we want a 220W output at 220V then we need 1A at the output. Then at the...

sample of 60W Inverter Circuit

Above circuit is a inexpensive completely transistorised inverter circuit ideal for driving medium loads of the order of 40 to 60 watts working with battery of 12V, 15 Ah or bigger power capacity. Transistors T1 and T2 (BC548) make a 50Hz multivibrator. For having proper frequency, the values of resistors R3 and R4 may have to be modified after testing. The complementary outputs from Collectors of transistors T1 and T2 are provided to PNP darlington...
