　　IGCT的应用特性

　　IGCT是通过在门极可关断晶闸管（门极可关断晶闸管，GTO）中引入缓冲层、阳极透明发射极结构，并将门极驱动电路集成，从而使IGCT不仅具有大电流、高火灾电压、低通态压降，同时还具有较高的开关速度、高可靠性等优点。IGCT目前产品的可关断电流达到8kA。

　　相对于IGBT，IGCT具有非常高的浪涌电流承受速度，4英寸器件可耐受10ms的30kA以上的正弦暂态电流。从开关速度来看，IGCT的开通和关断均要慢于IGBT事实上，对于IGCT 5SHY40L4511和压接式IGBT 5SNA1300K450300，若考虑2800V/1300A的关断电压和电流，IGCT的关断电压约为5J，而IGBT约为6J，因此另外，IGCT在导通2kA电流时的通态电压降达到1.5V，而IGBT则为3.0V，因此IGCT通态损耗也略低。18 - 19 ]。但是，由于IGBT是电压源型器件，门极驱动功率远低于恒定IGCT。

　　从成本上看，目前同等容量的IGCT售价约为压接式IGBT的1/2，而模块式IGBT价格相对较低。事实上，由于当前IGCT的应用不如IGBT广泛，使得市场价格偏高，如果实现更大规模的应用，IGCT成本还可以降低。

　　总的来说，IGCT的开关频率、驱动功率等性能表现要逊于IGBT，但在容量、通态损耗、开关损耗、成本等表现性能方面具有潜在优势。

　　Application characteristics of IGCT

　　IGCT introduces buffer layer and transparent anode emitter structure into gate shut-off thyristor (GTO), and integrates gate drive circuit, so that IGCT not only has high current, high fire voltage, low on-state voltage drop, but also has high switching speed, high reliability and other advantages. IGCT's current products have a maximum shut-off current of 8kA.

　　Compared to IGBTs, IGCT has a very high surge current withstand speed, and 4-inch devices can withstand sinusoidal transient currents of more than 30kA at 10ms. In fact, for IGCT 5SHY40L4511 and crimped IGBT 5SNA1300K450300, if the shutdown voltage and current of 2800V/1300A are considered, the shutdown voltage of IGCT is about 5J, while that of IGBT is about 6J. Therefore, in addition, the on-state voltage drop of IGCT when conducting 2kA current is as low as 1.5V, while that of IGBT is 3.0V, so the on-state loss of IGCT is also slightly lower. 18-19]. However, because IGBTs are voltage source devices, the gate drive power is much lower than that of constant IGCT.

　　From the cost point of view, the current IGCT price of the same capacity is about 1/2 of the crimped IGBT, and the modular IGBT price is relatively low. In fact, because the current application of IGCT is not as extensive as IGBT, the market price is high, and the cost of IGCT can be reduced if a larger scale application is achieved.

　　In general, the performance of IGCT such as switching frequency and driving power is worse than that of IGBT, but it has potential advantages in performance such as capacity, on-state loss, switching loss and cost.

　　What is the difference between DCS and PLC?

　　1. In terms of development:

　　DCS from the traditional instrument panel monitoring system development. Therefore, DCS from the innate more focused on instrumentation control, such as our use of YOKOGAWACS3000 DCS system does not even have the limitations of the number of PID (PID, Proportional Differential Integral algorithm, is a control valve, inverter closed-loop control of standard algorithms, usually the number of PID determines the number of regulating valves can be used).

　　PLC from the traditional relay loop development, the initial PLC does not even have analog processing capabilities, therefore, PLC from the beginning of the emphasis on the logic operation capabilities.

　　2, from the aspect of system scalability and compatibility:

　　A wide range of control products on the market, whether DCS or PLC, there are many manufacturers in production and sales. For PLC systems, there is generally no or very little need for expansion, because the PLC system is generally aimed at the device to use. Generally speaking, PLC also rarely have compatibility requirements, such as two or more systems require resource sharing, for PLC is also very difficult. And PLC generally use a dedicated network structure, such as Siemens MPI bus network, or even add an operator station is not easy or costly.

　　DCS in the development process is also each manufacturer's own system, but most of the DCS system, such as Yokogawa YOKOGAWA, Honeywell, ABB, etc., although the system's internal (process level) communication protocols are not the same, but the operating level of the network platform coincidentally chose the Ethernet network, the use of the standard or deformation of the TCP / IP protocol. This provides easy scalability. In this kind of network, the controller, computer all exist as a node, as long as the network reaches the place, you can arbitrarily increase or decrease the number of nodes and arrange the node position. In addition, based on the open protocols such as OPC and DDE of the windows system, the systems can also communicate easily to realize the sharing of resources.
