      Plexim is expanding its PLECS product line with real-time hardware to provide a complete and one-stop solution for modern power electronics development teams. By Beat Arnet and Felix Prausse, Plexim GmbH Introduction Designing power converters is a complex task requiring advanced tools and processes. Power converters are sophisticated systems composed of multiple [...]

Reading Between the Lines

Posted on 20 January 2016

      Using data sheets correctly when selecting resistors When selecting a resistor for your application, there is more to bear in mind than you might think. In order to make a preliminary choice using a product data sheet, developers need certain background information and have to calculate some dimensions themselves. An example shows [...]

Web-based Simulation Tool to Simplify IGBT Selection and Thermal Design in Minutes

Posted on 16 April 2015

      By Kristofer Eberle, Plexim and Jiangmin Chunyu and Andrea Gorgerino, International Rectifier, An Infineon Technologies Company For a given voltage, current rating and package type, there can be many possible IGBT candidates. Additionally, the designer has to ensure that the power stage operates reliably within the thermal constraints. To alleviate these two [...]

LLC Resonant Converter Simulation Using PLECS

Posted on 03 December 2014

      Soft-switching capabilities of resonant converters allow for power supplies with smaller packaging and higher power density. PLECS is a simulation tool developed for power electronics engineers that offers very efficient and robust modeling of power supplies with multi-physical domains and associated controls. In this study, a full-bridge LLC converter with variable-frequency operation [...]

Analysing Thermal Performance of Intelligent Power Modules for Better PCB Design

Posted on 02 October 2014

      Intelligent power modules are the designer’s choice for low-power motor-drive applications, particularly where cost and size constraints are tight. A new study of module thermal performance under various operating conditions helps designers to predict operating temperature, power and PCB design accurately for optimum reliability, cost and size. By Stefano Ruzza & Marco [...]

Efficient Microcontroller Peripheral Modeling with PLECS

      A look at how to implement an analogue-to-digital conversion in a low bandwidth application By Mark Pallones, Kristine Angelica Sumague and Mike Gomez, Microchip Implementing an analogue-to-digital conversion in a circuit is one of the most common tasks facing designers and one that can be done in various ways. But for many [...]

Fast Compensator Design and Optimization for Power Converters based on Graphical Visualization

Posted on 30 May 2014

      Shaping the control-to-output frequency response is a widely used technique for compensator design. The most important factors of the design process are phase margin (PM) and cross-over frequency (fc). Are all combinations of phase margin and cross-over frequency feasible? Can a high cross-over frequency and a phase margin of 45º always be [...]
