High voltage inverter circuit diagram
This inverter circuit works with a transistor and transformer and other components to increase the voltage becomes high. Input supply voltage ranging from 3V to 6V DC, later it was raised to high voltage AC. However, in this inverter circuit output current is very small, probably under 0.1A even smaller. However, its use you can apply it on a fluorescent lamp 10W maximum power only, and that too takes time to switch on fluorescent lamps.Part List
R1 = 4K7
R2 = 2K2
R3 = 330K
C1 = 100nF
C2 = 100nF 275V
C3 = 0.22uF 275V
Q1 = D506
L1 = 100 times winding, with 0.8mm diameter copper wire
L2 = 50 times winding, with 0.8mm diameter copper wire
L3 = 5000 times winding, with 0.4mm diameter copper wire

Super High Power Portable TV and FM Jammer Wiring diagram Schematic
This is the Super High Power Portable TV and FM Jammer Circuit Diagram. There are still neighbors that keep annoying you by having loud the TV or the radio? Well I have you the solution. In fact all neighborhood will face your jamming waves at their TVs and radios, so be careful.
This Jammer is the improved version of the old `TV and FM jammer schematic` with the difference of much higher power. Many of you where asking for a stronger and wider effect but to be as portable as can be. Looking at the schematic you can see that, only the parts are changing keeping the basic schema intact. Have in mind that this version needs heat sink and antenna to keep the transistor alive.
Super High Power Portable TV and FM Jammer Circuit Diagram
The power source comes from three 9 volt batteries in series, so we use 27 volts at input, and we get a power full 2,5 Watts at output.
You are going to need 70cm to 2 meter simple wire antenna.
As for the transistor Q its the 2N3553. Its a RF Power Silicon NPN Transistor in a TO39 type package designed to be used in amplifiers and oscillator applications in military and industrial equipment.
Usually found as an output driver, or in predriver stages in VHF equipment, but because here we dont care about the modulation of the signal but just the power, thats why we use it as a first and final output driver.
The transistor is specified at 175MHz and 28V to give: Output Power: 2.5W, Minimum Gain: 10dB and Efficiency: 50%.
The parts are: R1=10k, R2=2,2K, R3=100 C1=47uF/50V, C2=2.2nF, C3=10pF, SW=switch, B=Battery 9V.
The coil L should be closely wound 5 turns (start tunning with the closely wound distance of turns and then play with it and the C4 capacitor, to find the desired frequency )of enameled copper wire 1.5mm and internal coil diameter of 1cm (leads 2x20mm).
The variable capacitor C4 should be air trimmer capacitor rating 4 to 30 pf or the closest to this value.
Connect the batteries in series place the best heat sink for TO39 case you can get and pack it all in a small plastic box. Enjoy ;)

2SC5200 and 2SA1943 high fidelity power transistor
Here are two transistors manufactured by Toshiba. 2SC5200 and 2SA1943 transistor pair has been widely applied or used in the amplifier power amplifier because the transistor has a large power, and also not too expensive than other large power transistors. This transistor has the advantage of High breakdown voltage: VCEO = 230 V (min), Suitable for use in 100-W high fidelity audio amplifiers output stage. For more information, please see datasheet below.

Build a 13KV High voltage Power supply Wiring diagram Schematic
This 13KV High voltage Power supply Circuit Diagram has an inverter around Q1 that supplies 150-V pulses to the converter of SCR1 and C2. The output of ?2 is a 4.5-kV pulse that is multiplied by the voltage-tripler network (right) to produce 13.5 kV. R1 is a 3k to 500K CT transistor audio transforfiler, L2 is a flash tube trigger transformer with a 6-kV secondary.
