Thecircuitof integrated flip-flop TDA1024 will be connected afterswitch S closed. Whenever thepower gridvoltage is zero, it willproducea triggering pulse, and make the thyristor conduction, load current flow through the RL. When switch S is off, there is no current in load. In order to protect the Triac, it should be connected a varistor at both ends in parallel. The maximum power output of the circuit is 1400W, for example, if it uses thyristor BT139, the output power is up to 2000W; if it uses BTW41, the output power can be up to 5000W.
