Rangkaian Generator Tegangan Tinggi

First of all let me admonish you that this ambit is a actual alarming one. The achievement voltage of this ambit is in Kilo volts and it can actively abuse you or annihilate you. Try this ambit alone if you accept abundant acquaintance ambidextrous with aerial voltages. I accept no albatross on any hazards acquired by the circuit. Be actual careful. This is a apprehensive request.

The ambit accustomed actuality has three sections namely oscillator, switching date and a footfall up stage. The oscillator is body about a NE555 timer operating at 25 KHz. The achievement of the NE555 accompanying to the abject of the ability transistor TIP3055 which is the switching device. The ability transistor drives primary of the footfall up agent at 25 KHz and as a aftereffect a aerial voltage will be induced beyond its secondary.

Notes.

* A 12V advance acerbic array can be acclimated for powering the circuit.

* TIP3055 charge be army on a calefaction sink.

* T1 can be an EHT (extra aerial tension) agent acclimated in television sets.

* For an EHT from 20inch TV, the achievement voltage will be 8 to 10 KV @12V accumulation voltage.

* This ambit is not an able one and is not acceptable for any austere applications.

* Once again, be actual accurate with this circuit!.

RANGKAIAN SINYAL GENERATOR IF SEDERHANA

Here is a versatile circuit of IF signal generator which may be of interest to radio hobbyists and professionals alike.Transistors T1 and T2 form an astable multivibrator oscillating in the audio frequency range of 1 to 2 kHz. RF oscillator is built around transistor T3. Here again a 455kHz ceramic filter/resonator is employed for obtaining stable IF. The AF from multivibrator is coupled from collector of transistor T2 to emitter of transistor T3 through capacitor C3. The tank circuit at collector of transistor T3 is formed using medium wave oscillator coil of transistor radio, a fixed 100pF capacitor C5 and half section of a gang capacitor (C6).

The oscillator section may be easily modified for any other intermediate frequency by using ceramic filter or resonator of that frequency and by making appropriate changes in the tank circuit at collector of transistor T3. Slight adjustment of bias can be affected by varying values of resistors R6 and R7, if required

1Hz to 1MHz Function Generator With XR-2206 IC

Physical View

An indispensable tool for any electronics lab is the function generator. It enables a variety of measurements and experiments. The module described here is based on the industry standard and build .Baustein XR2206 is extremely compact and inexpensive. It provides sine and triangular voltages at about 1Hz to 1MHz, depending on the timing capacitors used. Over two potentiometer, the amplitude and the frequency can be adjusted. About trimmer can also be changed nor the purity of the sine signal and the offset of the output voltage.

Here the diagram, it is based on the standard application circuit in the data sheet:



The structure can be very compact on a board. The bands will be selected by a DIP switch. Alternatively, you can instead of the DIP switch and use a step counter, which is conducted through wires to a front panel.

The module is operated with about 12VDC. In a virtual mass is formed at half voltage, the mass output of the output signal is therefore on this potential. This must be taken when connecting the module!

With appropriate matching circuitry provides the sinusoidal signals with less than 0.5% THD.
