What does scr mean?

Scr refers to silicon controlled rectifier.

SCR is short for silicon controlled rectifier and silicon controlled rectifier. Thyristor rectifier is a kind of power control appliance based on thyristor (power electronic power device) and with intelligent digital control circuit as the core. It has the advantages of high efficiency, no mechanical noise and wear, fast response, small size and light weight.

In the waveform diagram of controllable rectifier circuit, it is found that when the thyristor bears DC voltage, the first trigger pulse is sent out at the same time every half cycle, that is, the control angle α is equal to the conduction angle θ.

In order to realize the "controllable" output voltage of the rectifier circuit, it is necessary to make the trigger circuit send out the first trigger pulse at the same time every half cycle when the thyristor bears DC voltage. This cooperative working mode is called trigger pulse synchronization with power supply.
