ABSTRACT
HV Power Supply is needed in Gieger Muller tubes which is an instrument to measure the dose count and dose rate of nuclear radiation in a particular body, depending on the purpose and body there are different kinds of Gieger Muller tubes having different specifications as well. These instrument need High Voltage Power Supply to drive them but different values of voltages are needed for different purposes so instead of changing the voltage every time the programmable power supply is used. HV Module (CA 10) is used to convert low voltages to high voltages by the factor of 200 (i.e if 5V input is given it converts it to 5*200=1000V). The input of module is programmed by PIC Microcontroller and then further interfaced with eeprom, DAC …show more content…

Nuclear Radiation Management & Application (NRMA)
NRMA Division is working on R & D in the field of dosimeters, dose rate meters, area monitors and radiation detectors. Facilities are established for the calibration and testing of radiation monitors which includes thermo luminescent dosimeters based on personnel monitoring services. The facilities are made traceable with the accreditation by national organisations (NABL / BARC). Respective training courses for people in armed forces in Nuclear Defence and Radiological Safety are being continuously conducted. Scientists of DLJ represent many number of National Committees related to field of nuclear defence/safety.
Desert Environment Science & Technology (DEST)
DEST Division is working in the R&D in the fields of heat, water& soil to improve the working conditions of the troops operating under harsh conditions of the Desert. Basic and as well as applied research is being carried out which is leading to development of technologies related to terrain management, water and heat for military …show more content…

The primary function of a power supply is to convert one form of electrical energy to another and, as a result, power supplies are sometimes referred to as electric power converters
Types of electronics power supply
There are three major types of power supply that can be used in this project. Each have their own advantages and disadvantages and as a result each is used for purposes under different circumstances.
The three major types of electronics power supply are:
Rectified and smoothed power supply: These electronics power supplies are the simplest types, and are generally used for non-critical applications where performance is not a major issue. This type of power supply was widely used in thermionic valve or vacuum tube equipment as it was not so easy to regulate supplies, and often the requirements were not so critical.
Linear regulated power supply: This form of electronics power supply is able to provide a very high level of performance. However the fact that it uses a series regulator element means that it can be comparatively inefficient, dissipating a significant proportion of the input power as heat. Nevertheless these power supplies can offer very high levels of regulation with low values of ripple,
