Abstract
PURPOSE: To control temperature through a combination of ON-OFF control and proportional control by controlling a Triac connected to load in series with a switching element in which a capacitor and a charge and discharge circuit are connected to the input end.
CONSTITUTION: A Triac 5 is connected to an AC power 1 together with an electric heater load 4 and a switching element 7 in which a capacitor C2 and a bridge circuit consisting of resistors R2 and R3 and diodes D3 and D4 are set up at the input end. The first and second transistors 10 and 11 to form a zero cross detection circuit are set up to control the Triac 5. As a result, output can be controlled up to 100% by making charge time constant and varying discharge time and large current also be opened and closed by eliminating noise at ON initial time
