RAFI tactile switches are high-quality and innovative switching solutions that are widely used in various fields and industries. These are electromechanical components that allow human interaction with electronic devices by pressing their surfaces.

With this approach, relatively large and complex PCB designs are required to meet all of the spacing and layout requirements of the drivers and discrete power devices combination. Another equally perplexing problem is maintaining consistent performance and reliability when the characteristics of the drivers and power devices are not properly matched. An alternative solution to these problems is to use an integrated power module that contains all the required power devices along with matched...

The 7th gen. NX-type IGBT modules in the 650V, the 1200V and the 1700V categories have been developed in a comprehensive line-up to provide the best solution for different power classes. The new CIB (Converter Inverter Brake) modules which have been recently developed and the 800A / 1200V half bride module will further extend the line-up. The 7th gen. NX-type IGBT modules and the G1-series IPMs are based on the SLC package technology offering a remarkable advancement in the level of the...

In the second half of the 1990s, development and commercialization of IGBT power modules for high voltage ratings as 2500 V and 3300 V has started. Originally, these HV-IGBTs were designed as GTO replacement for high-power and high-reliability applications like for example railway traction inverters [1]. Additionally, the use in many other high-power applications has followed.

Power module performance affects the overall efficiency of the power electronic system. Accordingly, power modules have to be carefully chosen for a given application depending on various electrical and thermal performance parameters. Mitsubishi Electric had launched the latest 7th generation industrial IGBT modules in the 650 V and 1200 V classes [1]. These modules have already been well accepted by the market due to the advantages with regards to the key system requirements: high power...

Each CIB module consists of an integrated 3 phase inverter part, a converter (3 ph diode rectifier) part and a brake chopper part. The line-up of the latest NX7 CIB modules is shown in Figure 1. The NX7 CIB modules utilize the latest 7th generation CSTBT™ IGBT along with the RFC (Relaxed Field of Cathode) diodes. The electrical characteristics of the new thin wafer 7th generation chips have been tuned for the reduction of overall power losses.

A wide motor power range up to 15 kW for different motor voltages is covered by the DIPIPM™ product family. These products are now used in numerous applications such as servo and standard drives, air conditioning systems, refrigerators, fans and washing machines.

Applications like wind energy converters, central photovoltaic inverters and industrial drives require power modules with the highest power density, high reliability, and scalable power ranges with a standardized outline in the voltage classes of 1200V and 1700V. To fulfill such requirements, the LV100 power module is based on same outline and internal layout concept as the well-known HVIGBT LV100 module. This concept is convincing because it is based on a standardized package outline while...

In general a problem occurs when 3-level NPC topologies are developed using several standard half bridge power modules. A series connection of IGBT modules results in high stray inductances which in combination with high switching di/dt cause high switching overvoltages [2]. IGBT modules with an integrated NPC topology phase-leg containing 4 IGBT and 6 diodes potentially have lower stray inductances but are not available for high current ratings and are more expensive due to the complex...

Conventionally available IGBTs with 1700 V blocking voltage are designed for the requirements of motor control application in 690 VAC networks where DC-link voltage is typically about 970 V and maximum below 1200 V. For renewable applications, higher DClink voltage is required going up to 1500 V which is the limit of the low voltage directive (2014/35/EU). Hence, a new 2.0 kV class IGBT in the LV100 housing has been developed and evaluated under the requirements of renewable applications such...

The demands have grown on EMC know-how in modern product development. ICs today are much more sensitive and the number of EMC standards and directives which have to be complied with has risen too. This article deals with the possibilities open to an electronics' developer nowadays to optimise devices and circuits in terms of EMC.

Imagine for a moment that you are trying out a brand new car: you slide into one of the ergonomic seats, start the engine and, to make things perfect, would like to listen to some music. But when you switch this on, you suddenly notice interesting side effects. The light comes on in the passenger compartment, for example. Or the radio starts whistling and whimpering.

Explosion-proof signaling tower equipped with universal and energy-saving LED lighting with vertically and horizontally cut lenses. The lenses and body are made of polycarbonate with properties resistant to difficult conditions.

EMC tests identify potential EMC problems encountered by microcontrollers in practice. Electrostatic discharge is an issue of particular concern for circuits that include microcontrollers. ESD can be generated in practice in various ways such as static electricity that builds up on persons or frictional electricity that develops on conveyor belts, packaging machines, etc. The resilience of the electronics is tested with the test method according to IEC 61000-4-2 / HMM before the electronic...

Complex devices with integrated circuits and a low supply voltage increasingly fail interference immunity tests. The localisation and elimination of weak points is a real challenge in such complex devices. The fast, specific and hence cost-saving elimination of weak points requires effective strategies and appropriate equipment for systematic immunity analysis on the board level.

If you are using fluorescent lighting in hazardous areas then you need to take actions right now.

Pressure sensors are an essential element of automation of ventilation systems. These sensors are designed to measure air or gas pressure and provide accurate readings to the control system. Automation of ventilation systems is becoming more and more important in modern buildings because it allows better control of air quality and energy efficiency. Pressure sensors are used to monitor pressure in channels, pipes and other elements of the ventilation system. They can detect pressure changes...
