Abstract

An amplifier arrangement for operation at supply voltages of at least 100V and at output powers of at least 1 kW includes a half-bridge formed from two switching elements connected in series, two supply voltage terminals, and an output connection between the switching elements. A bypass capacitor is in parallel with the switching elements, and a current path is through the switching elements and the bypass capacitor, where the current path has a length of 10 cm or less, the half-bridge and the bypass capacitor are arranged on an area of 30 cm2, and a resonant circuit formed by capacitances and inductances in the current path has a resonance frequency of 100 MHz or greater.
