main parameter
electric current
1. Rated on-state current (IT) is the maximum stable working current, commonly known as current. The IT of commonly used silicon controlled rectifier is generally from one ampere to tens of amperes.
2. Reverse repetitive peak voltage (VRRM) or off state repetitive peak voltage (VDRM), commonly known as withstand voltage. The VRRM/VDRM of commonly used silicon controlled rectifier is generally from several hundred volts to one thousand volts.
3. Control pole trigger current (IGT), commonly known as trigger current. The IGT of commonly used silicon controlled rectifier is generally several microamps to tens of milliamps.
4. The average value of the current allowed to pass through the cathode and anode under the specified ambient temperature and heat dissipation conditions.
purpose
The most basic use of ordinary thyristor is controllable rectification. The familiar diode rectifier circuit belongs to uncontrolled rectifier circuit. If the diode is replaced by a thyristor, a controllable rectifier circuit can be formed. Take the simplest single-phase half-wave controllable rectifier circuit as an example. During the positive half cycle of the sinusoidal AC voltage U2, if the control pole of VS does not input the trigger pulse Ug, VS still cannot be connected. Only when U2 is in the positive half cycle and the trigger pulse Ug is applied to the control pole, the thyristor is triggered to be connected. Draw its waveforms (c) and (d). Only when the trigger pulse Ug arrives, the load RL will have voltage UL output. Ug arrived early, and the thyristor turned on early; When Ug arrives late, the thyristor will turn on later. By changing the arrival time of the trigger pulse Ug on the control pole, the average value UL of the output voltage on the load can be adjusted. In electrical technology, the half cycle of alternating current is often set at 180 °, which is called electrical angle. In this way, the electrical angle experienced from zero to the moment of the trigger pulse is called the control angle in each positive half cycle of U2 α; The electrical angle of thyristor conduction in each positive half cycle is called conduction angle θ。 Obviously, α and θ Both are used to indicate the conduction or blocking range of the thyristor during the half cycle of bearing the forward voltage. By changing the control angle α Or conduction angle θ， The controllable rectification is realized by changing the average value UL of the pulse DC voltage on the load.
1: Low-power plastic-encapsulated bidirectional thyristor is commonly used as acoustooptic lighting system. Rated current: IA is less than 2A.
2: large; Medium-power plastic-sealed and iron-sealed thyristor are commonly used as power-type controllable voltage regulating circuits. Like adjustable voltage output DC power supply, etc.
3: High-power high-frequency thyristor is commonly used in industry; High frequency smelting furnace, etc.
