Abstract

Bei einem erfindungsgemäßen Leistungssteuergerät (11) ist es durch spezielle Ausgestaltung von dessen Heizeinrichtung (25) möglich, diese durch eine Steuerung (53) zum gezielten Abschalten eines Geräteschalters (12) des Leistungssteuergerätes zu veranlassen. Dazu wird von der Steuerung (53) über Halbleiterschalter (S1,S2) eine zusätzliche Heizleistung in der Heizeinrichtung (25) aktiviert. Das kann entweder durch einen zusätzlich aktivierten Zusatzheizwiderstand (42) oder durch das Kurzschließen eines Teils (49) der Heizeinrichtung (25) geschehen.In the case of a power control device (11) according to the invention, it is by special design of its heating device (25) possible, this by a controller (53) for the targeted Switching off a device switch (12) of the power control device to cause. To do this, the controller (53) Semiconductor switch (S1, S2) an additional heating power in the heater (25) activated. That can be done either an additional activated additional heating resistor (42) or by short-circuiting part (49) of the heater (25) happen.

Eine gezielte Abschaltung kann beispielsweise von einem Topferkennungssensor (55) oder einer Maximalbetriebsdauerbegrenzung ausgelöst werden. Somit können die nach dem Stand der Technik für diesen Zweck benötigten Relais samt deren zusätzlicher Spannungsversorgung eingespart werden.
