With a Few Mouse Clicks to an Efficient Motor Control Design

Posted on 01 February 2009

      Application code generator makes FOC implementation an easy task With the XC878/886/888 MCUs the XC800 family from Infineon includes the industry first 8-bit microcontrollers providing the powerful Field Oriented Control (FOC) for complex and very efficient motor control applications. This advanced motor control technique will improve consumer and industrial drives addressing higher [...]

Power Modules for Electric and Hybrid Vehicles

Posted on 01 February 2009

      No baseplate ensures superior thermal cycling capability The urgent call for the reduction of CO2 emissions has led major automobile manufacturers to work on the development of new solutions for electric and hybrid drive vehicles. In order to develop a power semiconductor module for these applications, new solutions for module integration and [...]

Predicting Device Thermal Performance

Posted on 01 February 2009

      Using a simulation tool Predicting the thermal behavior of devices has become an issue of significance for power converter applications that require a tradeoff between efficiency, size and thermal and electrical performance. For such demanding applications, combined electrical-thermal simulation tools can significantly speed up the design process. One such simulation tool, PLECS, [...]

Optimising PFC Boost Converter Design

Posted on 01 February 2009

      Simulation model simplifies and speeds topology comparison High power Power Factor Correction (PFC) converters are increasingly important as equipment from welders to uninterruptible power supplies and refrigerators to air conditioners demands powers above 2kW from domestic power supplies. By Cesare Bocchiola, International Rectifier Corp.   And, while bridgeless and other low frequency [...]

Replacing Schottky Diodes with Super Barrier Rectifier Diodes

Posted on 01 February 2009

      The result is increasing power supply efficiency Schottky rectifiers have been used extensively in power supplies for the past 25 years. Schottky diodes feature a very low forward volt drop (VF), at reasonable leakage current, switching speeds that are in the nanosecond range, and provide a competitive advantage over conventional epitaxial p-n [...]

Low Voltage Paralleled MOSFET

Posted on 01 February 2009

      General suggestions for a good match In all types of power applications that use power MOSFET devices in switching operations, when the management of total current is too high for a single switch, and it is not possible to use a single power MOSFET (because the size of the device itself could [...]

Developments in Point of Load Regulation

Posted on 01 February 2009

      Supply rail count increased together with complex integrated circuits forming the load Point of load regulation has been used in electronic systems for many years especially where the load circuit is sensitive to noise. For example, in radio receivers it has long been a common practice to isolate sensitive loads from power [...]

New Record for Micromachined Energy Harvesters

Posted on 01 February 2009

      In the future, we will be surrounded by miniaturized autonomous wireless sensor nodes, integrated into our environment and measuring parameters in buildings, on our body, on machines. Today, these sensor systems still rely on batteries which hinder their downsizing and autonomy. By Els Parton and Rob van Schaijk, IMEC   For some [...]

Plug & Play in Power Electronics

Posted on 01 February 2009

      Designing a proper circuit to drive a given IGBT module Cost pressure, reduction of developing times and decreased time to market have lead to an increased number of standardized parts. Interfacing subsystems forming more complex devices are common among the automotive and communication industry. By Dr. Martin Schulz, Infineon Technologies   With [...]
