The 60 Hz inverter shown below is about as simple to make and as inexpensive as one could desire.
Yes, it is capable of providing some very useful services. Operating from an automobile battery, it can supply 50 W for the operation of such devices as an ac-dc radio, electric shaver, fluorescent lamp, small soldering iron, 40 W incandescent lamp, recorder, or portable phonograph. Its essential ingredients are a filament transformer and two general-purpose germanium power transistors.
Although this is a saturable-core oscillator, no separate feedback windings are employed. Rather, feedback is produced by cross-coupled connections in the manner of a multivibrator. At a full load, the efficiency is in the vicinity of 75 percent, and the output voltage is about 106 V.
The "mild" pi-section filter despikes the output waveform and causes a trapezoid wave, rather than the usual square wave, to be available at the output. This makes the device more suitable for the operation of radios, recorders, and other electronic equipment.
In this type of circuit, the efficiency, frequency, output voltage, and starting ability are interdependent to a marked degree. Accordingly, some experimentation with the biasing resistances may prove profitable.
It is likely, however, that only one of them, such as R1, might have to be modified. Insofar as possible, the biasing networks for the two transistors should be approximately balanced.
Otherwise, an unsymmetrical waveform, unequal transistor dissipation, and other malfunctions.can result.

Hello, my name is Jack Sparrow. I'm a 50 year old self-employed Pirate from the Caribbean.
Hey Kiran jc in your schematic if the curly line is the transformer what are the capacitors doing after that? And I also don't understand what is the curly line after the transformer
ReplyDeleteHey it's me again. I don't understand why are you lowering the power from 117vac to 100 vac
ReplyDeleteLove your blog, lots of nice circuits. Thank you Kiran.
ReplyDeletethis guy has copied this circuit from one of my earlier websites, in fact all his circuits are copied from different website and content plagiarized, I will soon file a complaint and get this blog removed.
