Abstract :
This paper describes the design and implementation of a prototype 30kW, 200kHz pulsed power supply. A power density greater than 100W/inch3 is achieved with the converter operating at a high ambient temperature of 65 °C, by utilizing various technologies on topology, control, devices, passives, and thermal management, which can help reduce the converter size. The experimental results demonstrate that the converter meets the performance requirements while achieving the high power density.
