Abstract (en)

[origin: EP1126591A2] The power regulation method uses an IGBT-module (10) and a choke coil (L) in series with the heating resistance (R), a capacitor (C) across the mains voltage rectifier (11) and a regulation device (16) supplied with the operating current and voltage for the current circuit of the heating resistance via a sensor device (14), for providing a control frequency for the IGBT-module. The output of the sensor device is supplied via a current limiter (18) to a driver (20) for controlling the IGBT-module. Also included are Independent claims for the following: (a) a power regulation device for a low-ohmic heating resistance; (b) an application of a power regulation device for metal, molybdenum silicide and silicon carbide heating resistance elements; (c) an application of a power regulation device for low-ohmic heating resistances for workpiece warming, paint drying, soldering, or a food cooking or clothes pressing appliance.
