Abstract
An aircraft induction oven excitation arrangement includes at least one connection for an on-board power supply system, at least one power supply rectifier that can be connected to a phase of the power supply system, a converter that is arranged downstream of the at least one power supply rectifier and that includes a switching element, a controller that drives the at least one converter, a rectifier that is arranged downstream of the converter in order to produce an intermediate circuit voltage, an inverter that is connected to the intermediate circuit voltage. The switching element has a turn-on resistance R≦about 0.1Ω and a self-capacitance ≦about 200 pF at voltages of ≧about 200 V across the switching element.
