TEMPERATURE CONTROL DEVICE Russian patent published in 1994 - IPC

FIELD: systems for regulating non-electric quantities in industry and domestic devices (electric irons). SUBSTANCE: device has auxiliary first transistorized switch connected between an output of comparator and corresponding terminal of output diagonal of diode bridge, an input being connected to first output of voltage limiter; second transistorized switch connected in output diagonal of the diode bridge, an input being connected to the comparator input. The comparator, setting and temperature-sensitive voltage dividers are supplied from the second output of voltage divider connected in the diode bridge output diagonal which is connected between the control electrode and anode of power triac. EFFECT: enhanced reliability. 1 dwg
