Space High-Voltage Power Module

Abstract

With the rapid development of the world’s aerospace technologies, a high-power and high-reliability space high-voltage power supply is significantly required by new generation of applications, including high-power electric propulsion, space welding, deep space exploration, and space solar power stations. However, it is quite difficult for space power supplies to directly achieve high-voltage output from the bus, because of the harshness of the space environment and the performance limitations of existing aerospace-grade electronic components. This paper proposes a high-voltage power supply module design for space welding applications, which outputs 1 kV and 200 W when the input is 100 V. This paper also improves the efficiency of the high-voltage converter with a phase-shifted full-bridge series resonant circuit, then simulates the optimized power module and the electric field distribution of the high-voltage circuit board.

High-Voltage Power Supply for High Repetitive Rate Marx Generator with Quasi-Resonant Zero-Current Switching Transistor Control Algorithm

“…For this purpose, high-frequency transformer-based converters are most commonly used. A literature review performed in the area of high-voltage power supplies for rapid capacitor charging showed that in most cases, topologies with full-bridge converters are used [12][13][14][15][16][17][18][19] due to the versatility of this topology and the possibility of implementing various control algorithms.…”

“…In [12][13][14], a simple hard-switched duty cycle control method was used, but this way of control may cause significant electromagnetic disturbance and large power losses [20]. Therefore, a method with phase-shifted modulation is much more often used [15,16]. In a large number of applications, a resonant converter can be found [17,18].…”
