This article is a high voltage, low current supply circuit is discussed. By convention, in order to better grasp the principles you are, we recommend you to combine text read schematics. Here's current requirement of a few microamps. In such an application, the high voltage between the basically there is a "real" line and ground. When these "live" wire is touched, the discharge occurs through the body resistance and it gives a non-lethal but deterrent impact intruders. This circuit is to create a single transistorised blocking oscillator. An important element in this circuit is a  transformer . It can be easily fitted in the ferrite core. Two "E" part of the core is face to face after adding enamelled copper wire wound first placed in it. Details of the transformer windings shown in the table. In this configuration, the primary winding and the feedback winding arrangement, so that the oscillation is maintained to ensure that once the supply is turned on. Note that if the oscillation does not occur in the "on" time, the feedback transformer winding or a primary winding terminal (but not both) should be reversed. The main oscillation amplitude is about 24 v (p p). This is amplified by a large transformer, step-up ratio we get about 800 v (pp) in two. A simple series voltage multiplier (called Cockroft-Walton circuit) is used to enhance this voltage step to the final current of about 2 kV. Output voltage, however, is not very good regulation. However, if there is a constant load, the final voltage can be adjusted for different supply voltages. Current configuration to 2 kV for the input DC voltage 15 v. If you are a first reading on this principle, we recommend that you carefully read several times in order to better fully grasp this simple but effective circuit..table
