2000v high voltage low current power

Description: A high voltage power supply can be a beneficial source that can be utilized in various applications such as biasing gas-discharge tubes and radiation detectors. This power supply can also be employed for property protection through the electric charging of fences. The electric current requirement for such applications is typically in the range of several microamps. In this context, high voltage exists between a live wire and ground. When this live wire is touched, the discharge occurs through body resistance, providing a non-lethal but deterrent shock to an intruder. The circuit is designed around a single transistorized blocking oscillator, with a crucial component being the transformer. This transformer can be easily fabricated using readily available ferrite cores. Two E sections of the core are joined face-to-face after winding the enamelled copper wire onto a former and placing it within the core.

A high voltage power supply is essential for various applications, including the biasing of gas-discharge tubes and radiation detectors. Its ability to generate high voltage with minimal current makes it suitable for applications requiring only several microamps. In security applications, this power supply can be used to electrify fences, creating a barrier that deters intruders without causing lethal harm.

The circuit typically employs a single transistorized blocking oscillator, which is a popular choice for generating high voltage due to its simplicity and efficiency. The blocking oscillator operates by switching the transistor on and off rapidly, leading to the generation of a high voltage pulse across the transformer.

The transformer plays a pivotal role in stepping up the voltage to the desired level. It can be constructed using ferrite cores, which are preferred for their high magnetic permeability and low losses at high frequencies. The construction involves using two E-shaped ferrite sections, which are joined face-to-face. The enamelled copper wire is wound around a former, and this winding is placed within the core. The design ensures that the magnetic flux generated by the coil is effectively coupled through the ferrite material, enhancing the efficiency of the transformer.

When the live wire is connected to the fence, the high voltage generated can create a potential difference between the live wire and the ground. Upon contact with an intruder, the circuit completes, allowing a small current to flow through the body. The body resistance limits this current, ensuring that the shock is non-lethal while still serving as a strong deterrent.

In summary, the high voltage power supply circuit is a well-designed system that integrates a blocking oscillator and transformer to achieve its objectives. Its applications in biasing and security highlight its versatility and effectiveness in various fields.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.
