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 is designed to be supplied directly from the a
