Realization of a Temperature Based Automatic Controlled Domestic Electric Boiling System

This paper presents a kind of analog circuit based
temperature control system, which is mainly composed by threshold
control signal circuit, synchronization signal circuit and trigger
pulse circuit. Firstly, the temperature feedback signal function is
realized by temperature sensor TS503F3950E. Secondly, the main
control circuit forms the cycle controlled pulse signal to control
the thyristor switching model. Finally two reverse paralleled
thyristors regulate the output power by their switching state. In
the consequence, this is a modernized and energy-saving domestic
electric heating system.
