Power Supply Adapter

This is a basic knowledge about how to generate very high DC Voltage from 240V main AC home supply. The design of this circuit is very simple.

Here the circuit diagram of solid state tesla coil with 555 timer. Single transistor flyback driver induced a lot of complications on account of it really is operating principle. I received e-mails from those who had been unable to obtain it functional even after they are positive that their flyback and transistor is Okay. Moreover, because it is resonance frequency is determined by each individual a part of the method, any time you seek to draw an arc in the transformer, it alterations substantially in a lot of the circumstances. Simply because the operating frequency is vital for your security criteria, (each for mine and electrical power transistor's), I determined to generate it run on a continuous frequency and developed up yet another easy circuit, attempting to keep within the specified limits in the 555 timer.

This is a very simple high voltage power supply circuit for laser device. It is low cost circuit and very easy to built. This power supply can be built with common parts, most of which you probably already have in your junk box. The secret of this circuit is the transformer used. It is a common 9V 1A transformer unit, connected backwards for step up. Please note that some people may have trouble with this supply. This is due to the slight difference in transformers. 

Here the schematic design diagram of 600V power supply for QRO HF amplifiers. Amateur Radio Transmitters working with valves such as 807 or1625 operates properly using a plate voltage in between 600V to 700 Volts. The circuit described below is actually a full wave voltage doubler. The output voltage is twice the input voltage. For 230V AC input the output is going to be close to 600 Volts. Resister R1 is applied to minimize the initial high voltage and high currents. Capacitor C1, C2, C3 along with coils L1 and L2 form input line filter. The capacitors C4 and C5 protects diodes from high voltage transients on the AC line as well as minimizes inter carrier hum modulation of the R.F picked up by the mains. Capacitors C6 and C7 gives sufficient filtering for the output DC Voltage.

This is a high voltage, low current power supply circuit which will give you high power voltage about 2000V output from 15VDC input. A high voltage power supply can be a really beneficial source which could be properly utilized in a lot of applications like biasing of gas-discharge tubes and radiation detectors and so on. Such a power supply could also be utilized for protection of property by electric charging of fences. Here the electric current requirement is of the order of several microamps. In such an application, high voltage would basically exist in between a ‘live’ wire and ground. When this ‘live’ wire is touched, the discharge starts through body resistance and it provides a non-lethal but deterrent shock to an intruder. The circuit is built around a single transistorised blocking oscillator. An vital element in this circuit could be the transformer. It could be fabricated on quite easily available ferrite cores. Two ‘E’ sections of the core are joined face-to-face after t...
