A systematic method is proposed to select desired multi-elements resonant topologies, like three-element, four-element or more elements resonant topologies. The intrinsic characteristics of multi-element resonant converters are utilized for this classification and selection method. Three-element resonant tanks are grouped. One group is chosen for illustration. The characteristics of topologies in...
In this paper, a novel switching frequency control scheme to track the resonant frequency point (f0) is proposed. First, the synchronous rectifier (SR) gate driving signals are well tuned with proposed universal adaptive SR driving scheme by eliminating the body diode conduction. Then, the novel pulse width locked loop with digital implementation is presented to minimize the pulse width difference...
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...
