| Abstract |
This article shows how the GTO, used for natural switching in resonant converters will reach operating frequencies of around 20kHZ which are particularly interesting for induction heating. The reliability of the converter is improved and the problems posed by cooling are minimized. After the analysis of the different converter structures during continuous conduction, the authors highlight two set ups which appear well suited to operator frequencies extending from 10 to 20 kHZ; the current inverter and the voltage inverter for which self-pilot capability means that the load current is delayed with respect to the voltage. The principle of the controls, the implementation of these converters and the results of experiments are given in this article. |
