Overview
II TCA280A TRIGGER MODULE The TCA280A is a monolithic integrated circuit designed for thyristor and triac control.
It contains the following circuit sections: - d.
c.
power supply (intended for direct a.
c.
supply) - zero-crossing detector (for synchronization of the trigger circuit) - difference amplifier (used as a sensing amplifier) - ramp function generator (operating as the sawtooth oscillator in time,.
.
proportional control) - output amplifier (amplifying the trigger pulses and feeding the thyristor or triac gate) Various control modes possible when using the TCA280Aare: - phase control - synchronous on/off switching (static switch) - time proportional control The device i...
