Multi-output modular high-voltage power supplies for airborne and space applications

The high-voltage power supplies (HVPS) in airborne and space applications are commonly used for such devices as radars, lasers, communication systems, various scientific equipment, etc. Most of these devices contain vacuum tubes and other units which require, for their operation, more than one high voltage or floating voltages. A modular HVPS topology is a perfect solution for multichannel HVPS design. The high voltage power supplies described in this paper comprise no inertial parts. This makes them versatile and capable of operation under any possible conditions. A special design makes it possible to decrease leakage inductance and stray capacitance in the transformer-rectifier modules. High conversion frequency along with this unique mode of operation decrease the output filter capacitance. The lower amount of stored energy as well as extremely low response time makes it possible to achieve technical parameters which are impossible with conventional technology. HVPS designed by the authors were used in the former Soviet Union for a variety of space and military power applications
