Unidirectional way SCR SCR SCR, using a pointer table of R × 1 position, first find out the pros and cons to not pass two feet SCR C106M, remaining that must be controlled foot pole. Move the pointer multimeter red pen and black ink, respectively, then the two unreasonable level, then the control electrode connected with shorted black pen, the pointer will show the number of a certain angle of rotation, then turn off the control electrode of the black pen pointer if you keep trying to show the number does not move, the black pen then the anode, red pen then the cathode. What SCR in the circuit main purpose is Ug arrived early, thyristor of time early;? Ug late arrival, SCR conduction time later. By changing the time of the trigger pulse control on arrival Ug pole, you can adjust the output voltage on the load average UL (the size of the shaded area). In electrical technology, often alternating current half cycle for 180 °, called the electrical angle. Thus, each positive half cycle U2 SCR C106D, starting from a zero value to the electrical angle instant trigger pulse arrives experienced called control angle α; electrical angle of each positive half weeks thyristor called guide angle θ. Obviously, α and θ are used to denote the thyristor conduction or blocking withstand voltage of the positive half cycle of. By changing the control angle α or conduction angle θ, change pulsed DC voltage across the load average of UL, to achieve a controlled rectifier.
