60kv ignition coil driver circuit
The ignition coil driver circuit described is a highly regarded design, reportedly created by Jochen Kronjaeger. It is intended to operate from a 230V source, although a modified version can function effectively at 120V. The circuit requires two ignition coils...
0 1000 volt regulated high voltage
The input voltage for the high-voltage DC-DC converter is 12V AC at 800mA, which is then converted to DC using a 1A bridge rectifier diode. The output voltage of the converter can be adjusted within the range of 0-1000V DC....
Oscillators and Mixers
The emergence of modern radio and radar systems has created a demand for stable harmonic oscillations at specific carrier frequencies to facilitate the necessary modulation and mixing conditions. While early carrier frequencies primarily operated in the low to mid MHz...
simple electronic organ
This electronic organ is simple to construct and can provide hours of enjoyment, particularly for children. The circuit is fundamentally an emitter-coupled oscillator consisting of transistors T2 and T3. A square wave voltage can be sampled from the collector of...
High voltage switching stabilized voltage supply circuit
A high voltage switching stabilized voltage supply circuit is illustrated in the diagram. This is the switching power supply for an 80P type color television. It utilizes auto-excitation and a PWM circuit. The output is isolated from the power system,...
LC CHECKER
The circuit operates on the principle of the grid-dip or absorption effect, which takes place when a parallel resonant circuit is coupled to an oscillator operating at the same frequency. Transistor Q1 functions within a standard Colpitts oscillator circuit, maintaining...
Various Schematics and Diagrams
Energy storage capacitors in even the smallest disposable camera flash powered by a 1.5 V AA battery can be hazardous under certain conditions. Line-powered devices, regardless of size, may present additional risks due to high power at high voltage and...
Electronic Pest Killing Lamp
Working Principle: The circuit, as illustrated in figure 4-187, is composed of three main components: the power circuit, the pulse oscillator, and the high voltage generator. The power circuit includes components S, FU, TI, VD1-VD4, C1, C3, IC1, R1, and...
MicroFlash Schematic
The two resistors serve dual purposes. Firstly, they limit the current to a lower value in case of accidental contact with the circuit. Secondly, when the flash is activated, the main capacitor behaves like a short circuit to the power...
