Simple Circuit 12V to 120V DC DC Converter

Its a simple circuit of 12V DC to 120V DC converter. The circuit consists of two phases first phase of the investor base and then a rectifier and filter stage. IC1 NE555 is wired as an astable multivibrator operating at a frequency of 100 Hz and can be adjusted to the preset R1. IC1 output is coupled to the clock input of IC2 is a dual CMOS D flip-flop. IC2 divides the pulse train of 100 Hz IC1 2 50 Hz pulse trains that are 180 degrees out of the party and offered on the pin 1 and 2 of IC2.

When pin 1 is high transistor Q1 conducts and current flows through the upper half of T1 primary winding. When pin 2 is the transistor Q2 conducts and high current flows through the lower half of the primary coil T1. As a result of a voltage of 120 V AC are induced in the secondary of T1. This voltage is rectified with bridge D1 to provide a 120V DC output. Capacitor C2 is the DC input filter, while C3, C4 are the output filters.

Notes.

The circuit can be assembled on a vero board.
Q1 and Q2 require heat sink.
Output power of this dc dc converter is around 100 watts.
IC1 and IC2 are to be mounted on holders.
An optional 5A fuse can be added in series to the 12V supply line.
T1 can be a 9-0-9V /250V/3A mains transformer.
If 3A bridge is not available make one using 1N5408 diodes.
Out of the two Flip-Flops inside CD4013 only one is used here.
Output of IC1 must be set to 100Hz by adjusting preset R1

NE566 Function Generator Circuit Diagram

The NE566 Function Generator is a Voltage-Controlled Oscillator of exceptional linearity with buf fered square wave and triangle wave outputs. The frequency of oscillation is determined by an external resistor and capacitor and the voltage applied to the control terminal. The Oscillator CAN be programmed over a ten-to-one frequency range by proper selection of an external resistance and modulated over a ten-to-one range by the control voltage, with exceptional linearity.

Transceiver Homebrew QRP SSB 80M Band

Radio communication transceiver is a radio transmitter at the same time the plane doubles as a radio receiver used for communication purposes. It consists of the transmitter and the receiver are assembled in an integrated way. In mulamula generation, the transmitter or receiver or transmitter and receiver sections are assembled separately and is part of a stand sendirisendiri and can work well sendirisendiri Currently employed both parts are integrated in turn. Aircraft simple transmitter consists of an oscillator generating radio vibration and this vibration after vibration boarded with our voice, in a technique called dimodulir radio, then by the antenna is converted into radio waves and transmitted. As we know that the sound waves we can not reach long distances, although its power is quite large, while the radio waves with a relatively small force can reach a distance of thousands of kilometers. In order for our voice can reach a far distance, then our voice superimposed on radio w...
