  Smart Solution for 1500VDC 3-Level Central PV Inverters

  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...

  LV100 IGBT Modules for Best Performance in Renewable and Industrial Applications

  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...

  Questions on EMC

  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.

  New Development Tools and EMC Strategies in Step with Practical Electronics

  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.

  Effective Strategies for Interference Immunity Analysis on the Board Level

  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.

  Insulation monitoring relays

  Insulation control relays are devices that are used to monitor the condition of insulation in electrical systems. Their main task is to detect insulation damage that can lead to dangerous situations such as fires or electric shock. An example of such devices are Trafox products such as IM-04DCCT, IM-04PV or IM-05DCCT.

  Pressure sensors in HVAC applications

  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...

  Explosion venting in hazardous areas

  Actions taken to eliminate or reduce the risk of explosion should lead to the complete removal of the risk of explosion. In reality, however, it often happens that it is not possible to get rid of the explosive atmosphere, because these are the conditions of the processes being carried out or it would require huge financial outlays.
