Initially, consider that there is no voltage applied to the Gate terminal, at this stage the IGBT will be in a non-conductive state. Now if we increase the applied gate voltage, due to the capacitance effect on the SiO2 layer the negative ions will get accumulated on the upper side of the layer and the positive ions will get accumulated on the lower side of the SiO2 layer. This will cause the insertion of negative charge carriers in the p region,  higher the applied voltage VG greater the insertion of negatively charged carriers. This will lead to a formation of the channel between the J2 junction which allows the flow of current from collector to emitter. The flow of current is represented as the current path in the picture, when the applied Gate voltage VG increases the amount of current flow from the collector to the emitter also increases.The IGBT is classified as two types based on the n+ buffer layer, the IGBTs that are having the n+ buffer layer is called the Punch through IGBT (PT-IGBT), the IGBTs that does not have an n+ buffer layer are called the Non-Punch Through- IGBT (NPT- IGBT).

Based on their characteristics the NPT- IGBT, and PT-IGBT are named as symmetrical and nonsymmetrical IGBTs. The symmetrical IGBTs are the ones that have equal forward and reverse breakdown voltage. The asymmetric IGBTs are the ones that have a reverse breakdown voltage less than the forward breakdown voltage. The symmetrical IGBTs are mostly used in AC circuits, whereas the asymmetrical IGBTs are mostly used in DC circuits because they don’t need to support voltage in the reverse direction.The collector of the PNP transistor is connected to the NPN transistor through a JFET, the JFET connects the collector of the PNP transistor and the base of the PNP transistor. These transistors are arranged in a way to form a parasitic thyristor set up to create a negative feedback loop. The Resistor RB is placed to short the base and emitter terminals of the NPN transistor to ensure that the thyristor doesn’t latch-up which leads to the latch-up of the IGBT. The JFET used here will signify the structure of current between any two IGBT cells and allows the MOSFET and supports most of the voltage.

BT-50 * * expansion sensor is a sensor designed for the steam turbine industry to measure the expansion displacement of steam turbine units. It uses an intermediate frequency displacement sensor (LVDT) as the sensing element. The LVDT has a probe rod connected to the machine. When the casing expands, the feeler rod moves in the LVDT and the reference LVDT signal changes. After demodulation, the signal is output to the monitor for display and alarm.

The BT-50 * * expansion sensor is powered by 15-24VDC and outputs DC voltage signal. It has the characteristics of good remote transmission linearity, strong anti-interference ability, good reliability, and continuous use.


It is applicable to expansion measurement and protection of steam turbine cylinder.

control functions and integrate field devices and the other
nodes on the control network. The SX and SQ controllers
provide a choice to match the controller capacity to the
requirements of the process. They also provide new ease
of use features that eliminate mounting screws and accelerate
cabinet assembly.
Control strategies and system configurations created on
earlier DeltaV systems can be used with this controller.
The SQ controller provides all the features and functions
of the M-series controllers including support for CHARM
based Electronic Marshalling.
The control languages executed in the controllers are
described in the control software product data sheet.Scalable controllers. The SQ controller complements the
SX controller by providing a smaller controller platform at
a reduced price for those small to moderate applications:
„ Speed. The SQ controller supports all the features you’ve
come to expect from the DeltaV system: self-addressing,
automatic I/O detection. All these features are designed
to make your projects execute faster — just plug and play!
„ Redundant Architecture. The SQ controller supports
1:1 redundancy for increased availability. Redundant SQ
controllers can be upgraded to SX controllers online — robust!
„ Late Changes. You can easily upgrade an SQ controller
to an SX to handle project scope changes late in the
project. Simply replace the SQ with the SX and all existing
configuration, documentation and hardware design remain
the same — forgivingControl modules are automatically scheduled by the controller,
based on their assigned scan rates. This allows each control
function to be optimized based on the process dynamics.
Modules scan times can be set as fast as 100 ms, and as slow
as 60 seconds. The number of control modules that can be
assigned to a controller depends on the complexity and scan
rate of each module, and the available CPU and memory.
The SQ controller should be used for small to medium
applications with a maximum of 750 individual I/O signals.
The SQ controller is designed for harsh environments and
is rated for G3 corrosive environments, with an operating
temperature range from -40 to 70°C. It is ideally suited for
remote installation, close to the process equipment. For more
traditional installations with central marshalling cabinets,
CHARM I/O Cards can be mounted in standard I/O cabinets
providing Electronic Marshalling. CHARM I/O Cards can also
be used for highly distributed I/O applications.除了传统的I/O卡,本地总线还支持

Due to the way the Modicon Quantum HSBY system works, you will need to have the same number of PTQ-PDPMV1 modules in each chassis with each HSBY CPU.  In other words, if you put four (4) in one chassis, you must also have four (4) in the other chassis.  This is required because the PTQ-PDPMV1 modules can talk only to the CPU in the chassis in which they are installed.  They cannot talk to a CPU in another chassis, even if it is the primary CPU.支持HSBY的PTQ-PDPMV1的一个固件版本是1.15版。该版本以及1.25版之前的后续版本只能支持每个HSBY CPU机箱一(1)个PTQ-PPDPMV1模块。从1.25版及更高版本开始,每个HSBY机箱多可以有四(4)个PTQ-PDPMV1模块。

由于Modicon Quantum HSBY系统的工作方式,您需要在每个具有HSBY CPU的机箱中具有相同数量的PTQ-PDPMV1模块。换言之,如果您在一个机箱中放置四(4)个,那么在另一个机箱内也必须有四个。这是必需的,因为PTQ-PDPMV1模块只能与安装它们的机箱中的CPU通信。即使是主CPU,它们也无法与另一机箱中的CPU通信。The ProSoft ProTalkQ PTQ-PDPMV1 PROFIBUS Master solution is supplied with a comDTM driver that allows it to be used with any PROFIBUS device management software that uses comDTM technology.  Examples of such software are PACTware and Endress+Hauser Field Care.
