Rohde & Schwarz is set to unveil its latest advancements in power electronics testing at PCIM Europe in Nuremberg from June 11 to 13. This year’s exhibition will focus on solutions for testing and debugging the next generation of wide bandgap semiconductors in power electronic converters, addressing key industry challenges.
Experts from Rohde & Schwarz will share insights on applications such as inverter drive design, double pulse testing, and EMI debugging, using state-of-the-art test instruments. Visitors to booth 619 in hall 7 will explore these innovations under the theme “Moving to next-generation wide bandgap device testing & debugging.”
Highlighting the showcase will be the new MXO 5 and MXO 5C series oscilloscopes, the first eight-channel models from Rohde & Schwarz. These oscilloscopes leverage the company’s proprietary MXO-EP processing ASIC technology, achieving an unprecedented real-time acquisition rate of 4.5 million waveforms per second. The MXO 5C, designed for rack-mount applications, offers compactness without compromising on functionality. Both models support simultaneous real-time acquisition on four channels, processing 18 million waveforms per second, and feature 18-bit HD architecture for exceptional measurement precision. Attendees will learn how these tools can solve complex design challenges and gain a sneak peek at a revolutionary solution for measuring high common-mode voltages at high frequencies.
In the realm of power conversion, the MXO 5 oscilloscope excels in optimizing drivetrain and inverter performance by accurately characterizing gate driver signals, especially in multiphase systems. Its eight-channel capability provides a comprehensive view of all relevant signals, while the SmartGrid™ display configuration and built-in track functions facilitate detailed analysis of pulse width modulation (PWM). Paired with advanced high-voltage differential probes, the oscilloscope enables thorough examination of high- and low-side gate signals.
For double pulse testing, Rohde & Schwarz collaborates with PE-Systems GmbH to deliver a stable, precise methodology using high-quality power supplies and next-generation oscilloscopes. This approach ensures accurate, reliable, and fast measurements, essential for the dynamic and static characterization of wide bandgap components.
In the area of EMI debugging, the R&S RTO6 oscilloscope, equipped with advanced FFT functions, allows for precise noise analysis in power converter filter circuits. By separating common-mode and differential-mode noise, users can implement effective filters to reduce system noise. Rohde & Schwarz will demonstrate this capability through the analysis of conducted emissions from a 48 V to 12 V DC-DC converter for automotive applications.
Rohde & Schwarz, committed to creating a safer and more connected world, continues to push technological boundaries with its Test & Measurement, Technology Systems, and Networks & Cybersecurity divisions. The Munich-based company, privately owned, generated EUR 2.78 billion in net revenue for the 2022/2023 fiscal year and employs around 13,800 people globally as of June 30, 2023. For 90 years, Rohde & Schwarz has empowered customers across industrial, regulatory, and governmental sectors to achieve technological and digital sovereignty.
