High-voltage subsystems play a crucial role in the functioning of satellites and rockets. They are responsible for amplifying radio frequency signals, generating X-rays, measuring magnetic and electric fields, detecting and measuring charged particles, and providing propulsion. This review paper discusses the scientific instruments commonly used in satellite environments that operate with high-voltage power supplies, including TWTA, ion thrusters, lasers, X-ray spectrometers, magnetometers, electric field sensors, charge particle detectors, and electric propulsion units. The paper also discusses the critical design points that need to be considered for high-voltage power supply systems in space, such as component selection, layout and assembly design, and radiation hardening. The review provides insights into the challenges faced in designing and operating high-voltage power supplies in space and highlights the importance of addressing these challenges to ensure mission success. A prototype HVEPC was developed to cater high voltages of continuous wave TWT for space applications. The HVEPC was designed to withstand harsh environment of space for 15 years in-orbit life for GEO missions. © Anita Publications. All rights reserved.
