Abstract

This paper describes the design of an LCC resonant tank that is to be used in a 300kW modular power converter for an application in particle accelerators. The aim of the power supply is to provide a so-called RF cavity with 25kV DC and a current up to 8A. Modular approach is chosen for redundancy and availability. Each module is composed of a resonant tank with a step-up Medium Frequency Transformer with its secondary windings put is series. Full gain is ensured in the full operation frequency range considering component value inaccuracies and ageing of capacitors. The paper focusses on the design of the resonant tank and its implementation in a 100kW power module prototype.
