Current SCR is itself a quite advanced active emission control technology system that injects a liquid-reductant agent—automotive-grade urea in the form of diesel exhaust fluid (DEF)—into the ...

A series commutated SCR makes a very unusual Solid State Switch in this solar charge regulator control. Advantages include simplicity and robustness. The SCR performs (3) functions: switch, latch and ...

The main SCR conducts the charging current from the solar panel to the battery while a 2nd commutation SCR performs the function of commutating (turning off) the main SCR current at the end of the ...
