Don’t be Restrained by Power Constraints

Posted on 17 July 2012

      Battery powered devices must operate from a single charge. In a fast paced business such as integrated electronics, suppliers who don’t foresee significant sea changes in customer demand are at risk of missing opportunities, particularly if they’re not able to respond quickly and with the right solution. For some time, semiconductor providers [...]

Innovative Module Features for Advanced Inverter Designs

Posted on 17 July 2012

      PressFIT, Duplex-Frame Packaging and Shunts The most fundamental challenges in connecting power electronics to PCB materials relates to reliability and lifetime expectations. Today the majority of connections regarding power electronic modules of up to 200A rated chip current today consists of soft-soldered joints. Nevertheless, cost pressure and the demand to speed up [...]

Bucking the Trend

Posted on 17 July 2012

      Simplified design of electronic ballasts for HID lamps While offering benefits of efficiency, lifetime and good colour rendering high intensity discharge lamps (HIDs) present designers with the challenge of ballast implementation. Electronic ballasts are smaller, lighter and more efficient than electromagnetic ballasts but, to date, have been more complex to implement. By [...]

New Tool Easily Navigates the Efficiency Standards Landscape

Posted on 17 July 2012

      Platform to use Worldwide Energy-Efficiency Specs and Standards Since discovering that approximately 10% of the electricity generated for residential use is being wasted by devices that are turned off but actually continue consuming power, government agencies have been developing programs to improve the efficiency of Energy-using Products (EuPs). This focus on reduced [...]

Simulating Losses and Semiconductor Junction Temperature in Power Electronics

Posted on 17 July 2012

      Temperature rise in the SixPack IGBT module can be predicted within a few seconds. When it comes to the simulation of entire drive systems, the thermal cycling is becoming more and more a designers issue. The lifetime of semiconductor components is strongly depending on thermal cycling. Therefore a detailed analysis is required [...]

Efficient Pulse Frequency Modulation Mode for 6MHz Step Down Converter

Posted on 17 July 2012

      Modern cell phones tend to embed more and more functionalities while solution size is shrinking, driving innovation both towards smaller size and efficiency improvement. Texas Instruments’ new step down converter, TPS62620 is addressing size and efficiency issues by operating at 6MHz in PWM mode, allowing use of very small external components, and [...]

Energy Conversion

Posted on 17 July 2012

      Demanding challenges for Power Semiconductor Industry New environmental policies focus specifically on the global development of regenerative energies, in particular wind and solar-based power generation and the improvement of energy efficiency. Both aims have a considerable impact on power electronics, the original purpose of which is the efficient control and conversion of [...]

Conserving Energy through Statistical Adaptation

Posted on 17 July 2012

      Efficiency is becoming more relevant due to lack of available power With operating expenses becoming a larger part of equipment purchasing decisions, manufacturers have been continuously looking for ways to reduce the energy consumption of their products. Most look for architectural changes or lower power technologies to incrementally improve the efficiency of [...]
