Description

IGCT integrated Gate Commutated Thyristors (IGCT integrated gate commutated thyristors = gate commutated thyristors + gate units) is a new type of power semiconductor switching device developed by medium voltage inverter for use in large power electronics packages. It was proposed by ABB in 1997. IGCT has made great progress in power, reliability, switching speed, efficiency, cost, weight and volume, and has brought a new leap to power electronic complete sets. IGCT integrates the GTO chip with the anti-parallel diode and gate drive circuit, and then connects it with the gate driver in a low inductance mode at the periphery, combining the stable turn-off ability of the transistor and the advantages of the low on-state loss of the thyristor, and gives play to the performance of the thyristor in the on-stage, and presents the characteristics of the transistor in the off-stage. IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low on-off loss and so on, and has a good application prospect. IGCT has been used in power system grid devices (100MVA) and medium power industrial drive devices (5MW) IGCT has been successfully applied in the field of medium voltage inverter for 11 years (until 2009), because the high-speed switching capability of IGCT does not need buffer circuits, so the number of power components required is less, and the reliability of operation is greatly increased. Insulated Gate Bipolar Transistor (IGBT), It is a composite voltage-driven power electronic device composed of BJT(bipolar triode) and MOS(insulated gate type field effect tube), which has the advantages of high input impedance of MOSFET and low on-voltage drop of GTR. The driving power is small and the saturation pressure is reduced. The diode is added between the collector and the emitter, mainly for continuous flow, and due to the inductive load, the IGBT turn-off moment will produce a very high self-inductive reverse voltage at both ends of the IGBT, which may breakdown the IGBT. The parallel diode shorted out this "self-inducted inverting voltage", protecting the IGBT.

An Analog to Digital Converter (ADC) is an electronic device used to convert an analog signal to a digital signal. It usually exists in the form of a plug-in board, which can be connected to a computer or other control system for the acquisition and conversion of analog signals. 1. Analog signal acquisition: analog digital acquisition board converts analog signals to digital signals through the built-in analog-to-digital converter (ADC). It can receive analog signals from sensors, instruments and external signal sources, such as voltage, current, temperature, pressure, etc. The acquisition board has high speed and high precision sampling performance, and can continuously measure and collect analog signals in a certain range. 2. Digital signal output: After the analog signal conversion is completed, the analog digital acquisition board will transmit the converted digital signal to the computer or control system for further processing, analysis and storage. The digital signal output can be in the form of pulse code modulation (PCM), or other common digital signal formats. 3. Multi-channel and multi-function: analog digital acquisition board usually has a multi-channel input function, which can collect multiple analog signal sources at the same time. In addition, they usually have other functions, such as voltage amplification, filtering, sampling rate selection, etc., to meet the needs of different application scenarios. 4. Communication interface: Analog digital acquisition board usually provides a variety of communication interfaces, including PCI, PCIe, USB and Ethernet, in order to connect with the computer or control system. These interfaces provide convenient data transmission and control, making the integration of the acquisition board with other devices more flexible and convenient. 5. Application: analog digital acquisition board is widely used in various fields, such as scientific research, industrial automation, data acquisition, instrumentation and so on. They can be used for various types of sensor measurements and instrument monitoring, such as temperature measurement, pressure monitoring, vibration analysis, etc. When selecting the appropriate analog and digital acquisition board, the following factors need to be considered: sampling rate, resolution, number of input channels, power supply mode, communication interface and software support. These factors will vary depending on the specific application needs.

Analog refers to some continuous change of physical quantities, such as voltage, current, pressure, speed, flow and other semaphore, analog signal is the amplitude of continuous change with time signal, usually the voltage signal is 0~10V, the current signal is 4~20mA, can use the PLC analog module for data acquisition, which can be converted to digital quantity after sampling and quantization. When it comes to simulation, we have to mention AI and AO, and let's explain AI and AO below. AI and AO's explanation (1) AI signal: analog input The so-called analog quantity is 4-20mA or 0-10V current or voltage signal, input into the DCS, after transformation, restore the original value, such as the current value displayed in the DCS; The secondary value of the current transformer (5A) is converted into a 4-20mA signal by the current transmitter (5A corresponds to 20mA), which is input to the DCS cabinet, and the actual current value is displayed in the DCS after conversion. (2) AO signal: analog output In contrast to AI, AO is the DCS output 4-20mA or 0-10V signal to control the operating parameters of the device; For example, the speed control process of the frequency converter, taking 40HZ as an example, through remote DCS control, that given the parameter value: 40HZ, DCS also sends a corresponding analog current value, in the range of 4-20mA (20mA corresponds to 50HZ), the signal is passed to the controller of the frequency converter, and the frequency converter runs at 40HZ as required.
