The need to reduce Energy Consumption as well as CO2 emissions is driving the growth of power electronics and power converters. Two of the main power electronics design drivers are increased power conversion efficiency and consumption analysis.

Telford, 9th November Keysight has new and innovative solutions that address each stage of the power converter design cycle with test instruments in:

1. Power device and component evaluation

2. Design software simulation

3. Hardware design and debugging

4. Design validation and certification

Topic 1: Power Device & Component Evaluation Insights in selecting & evaluating the latest power devices (MOSFETs and IGBTs) to deliver a competitive design that can win in the market. In this stage of the design cycle engineers want to evaluate the latest power devices (MOSFETs and IGBTs) to use in the next generation of their power electronics designs to ensure they can deliver a competitive design that can win in the market. With the emergence of wide band gap (WBG) devices like Silicon Carbide (SiC) and Gallium Nitride (GaN) the task of power device evaluation has become much more challenging. The new technologies offer capabilities that lead to benefits such as increased efficiency and smaller form factors for designs. But these same benefits make evaluating them and integrating them into future designs more challenging as we will discuss.

Topic 2: Design Software Simulation Insights on how EDA tools can help reducing EMI issues in Power Electronics design. Power electronics designs and switching converters in particular are moving to higher frequencies. This has a direct impact on layout parasitics creating ringing effects. To overcome these challenges designers needs to simulate circuits with parasitic layout effects. This can easily be addressed with Keysight ADS integrating an EM field solver (to extract the parasitic from the layout artwork) with the circuit simulator. With these tools, Power Electronics designers can anticipate the real performance of their circuits including EMC/EMI. Areas covered will include Controller modeling options, Ripple and noise analysis – emphasis on HB (Harmonic Balance) and Gate driver modeling and design.

Topic 3: Hardware Design & Debugging Insights in Hardware design debugging and optimising. Upon completion of device selection and simulation modelling, Power Electronics engineers face a variety of challenges when doing Hardware design debug including in
• Optimizing your design and speeding up the design process
• Reduce costly design delays and rework with EMC pre-compliance testing:
• Simulating precise and complex control signals
• Reducing test complexity with flexible power dc sources

This paper will discuss a variety of tools are available in benchtop hardware and software spanning from DC to RF, that with differentiated capabilities targeted at power electronic designers to help them get the most efficient and reliable product to market fast.

Topic 4: Design Validation & Certification Validating full functionality and reliability of the design and Certification to Industrial & Military standards. Design validation involves the importance of reducing test complexity to speed up time to market, ensuring the reliability of your design, and measurement integrity when establishing specifications such as efficiency. Additionally, the device needs to conform to various standards and certification tests that may vary depending on the where the device or product is being used. In this section, this paper will cover:
• Power quality and efficiency for the design to meet regional test standards
• Verifying the reliability of your design
• EMC compliance testing
