Thyristor structure diagram Three, three state thyristors So how does a thyristor work? We can put it in one of three possible states, in which it is either completely off or fully on, meaning that it is essentially a binary digital device. 1. Thyristor positive blocking mode Normally, the thyristor shuts down when no current flows into the grid: no current can flow from the anode to the cathode. Here, you can think of a thyristor as two diodes connected together, with the top and bottom diodes both slanted forward. However, this means that the connections in the center are reverse-biased, so the current cannot flow from the top all the way to the bottom. This state is called forward blocking. Although it is similar to the forward deflection of a conventional diode, no current flows. Here, positive bias is achieved by connecting the positive terminal (a) to the positive terminal of the battery and the negative terminal (k) to the negative terminal of the battery, as shown below. In this case, join points J1 and J3 get a forward bias, and join points J2 get a reverse bias. Here, too, current cannot pass through the thyristor, except for tiny currents that flow as saturated currents, as shown by the blue curve in the feature curve below.

The Programmable Logic Controller was first introduced in the United States in the late 1960s, when it was called the Programmable Logic Controller (PLC), which was used to replace relays. To perform logical judgment, timing, counting and other sequential control functions. The concept of PLC was proposed by General Motors. The basic design idea of PLC is to combine the advantages of computer function perfect, flexible, universal and relay control system simple and easy to understand, easy to operate, cheap and so on, the controller hardware is standard and universal. According to the actual application object, the control content is compiled into software and written into the user program memory of the controller, so that the connection between the controller and the controlled object is convenient. 2.3 plc features and functions (1) The main characteristics of plc. The characteristics of plc are: reliable work, fast running speed, building block structure, flexible combination, good compatibility, simple programming and generation, rich, strong network function. (2) The main functions of plc. plc system can well complete the industrial real-time sequence control, condition control, counting control, step control and other functions; It can complete analog/digital (a/d), digital/analog (d/a) conversion, data processing, communication networking, real-time monitoring and other functions. Years of practice shows that plc, reliable, is designed for the factory, with reinforced components according to the requirements of the working environment, real-time scanning practice and fault diagnosis function, easy troubleshooting, won the preference of users. What makes a plc so reliable is a real-time core or operating system of executable relay logic, sequential function diagrams, function blocks, structured text, command catalogs, or a combination thereof. In case of failure, the built-in device can maintain mechanical damage and maintain an orderly and predictable sequence. 2.4 The development trend of plc: there are extremely fast logical operations and logic control, sequence control capabilities, reliability in discrete control, convenient and easy to learn programming methods, so that it has an undisputed position in the field of industrial automation based on discrete.
