Rohde & Schwarz will showcase its newest options and superior methods for testing and analyzing energy digital programs and parts at PCIM Expo 2025 in Nuremberg, Germany. On the firm’s sales space (corridor 7, sales space 166), the highlight might be on options using the corporate’s cutting-edge take a look at devices to deal with the challenges of debugging subsequent technology extensive bandgap semiconductors like GaN and SiC.
Rigorous testing and superior characterization strategies assist design engineers improve the efficiency, effectivity, and reliability of their energy digital designs based mostly on SiC and GaN gadgets, utilized in pioneering industries like e-mobility, renewable vitality or AI knowledge facilities. Rohde & Schwarz will convey a choice of its complete T&M portfolio to sales space 166 in corridor 7 of PCIM Expo 2025, going down from Could 6 to eight on the Nuremberg Exhibition Heart. The take a look at options are tailor-made for energy electronics functions the place excessive effectivity, quick switching speeds, improved energy density and high-temperature operation matter.
Broad bandgap evaluation
On the heart of the offered setups would be the R&S RT-ZISO remoted probing system from Rohde & Schwarz. This subsequent technology remoted probe has set new requirements with unprecedented accuracy, sensitivity, dynamic vary and bandwidth for extensive bandgap energy designs with SiC and GaN. Rohde & Schwarz will showcase the benefit of the R&S RT-ZISO over single-ended probes in a setup to research the switching conduct of a GaN-MosFET.
Double pulse testing
Double pulse testing is a technique for evaluating the switching efficiency of SiC and GaN based mostly energy gadgets. Rohde & Schwarz is collaborating with business knowledgeable PE-Programs GmbH for a secure and correct strategy to double pulse testing utilizing the MXO 5 subsequent technology oscilloscope from Rohde & Schwarz with eight channels together with the R&S RT-ZISO. At PCIM, guests can expertise correct, dependable and quick double pulse testing on 1200 V SiC gadgets from Wolfspeed, usually used as traction inverters within the automotive business.
Automated loadjump testing
Loadjump testing was once a time-consuming guide course of to confirm a Buck converter’s load step response at various enter voltage ranges, utilizing only some reference factors. For this utility, as nicely, Rohde & Schwarz collaborates with PE-Programs GmbH, who gives a take a look at automation software program. Together with the MXO 5 oscilloscope and the R&S RT-ZISO remoted probing system, this resolution not solely reduces total testing time but additionally maintains the identical variety of take a look at factors. At PCIM, the businesses show automated loadjump testing of a Buck converter of Monolithic Energy Programs, Inc. inside a voltage vary of 6V to 60V. The setup even permits for extra reference factors inside the identical timeframe and could be prolonged to incorporate temperature management, facilitating the total automation of enter voltage, load present, and temperature profile variations.
Element characterization
Rohde & Schwarz may even showcase its options for element characterization. The R&S LCX LCR meters with personalized impedance measurement features are appropriate for all discrete passive parts as much as 10 MHz. Customers can simply characterize the voltage dependence of capacitances in core parts of energy converters like MLCCs with the R&S LCX. Mixed with a sweep software program device, customers can carry out complete sweep measurements and show them in quite a few charts. The MFIA impedance analyzer from Zurich Devices AG is able to impedance spectroscopy for each low impedance parts comparable to shunt resistors and DC-link capacitors and excessive impedance programs. It gives measurement modes for impedance evaluation over frequency and time in addition to different options comparable to built-in oscilloscope and spectrum analyzer capabilities.
Dr. Philipp Weigell, Vice President of the Trade, Parts, Analysis & College Market Section at Rohde & Schwarz, explains: “PCIM Expo is a crucial venue for us to spotlight our developments in extensive bandgap semiconductor testing. Testing performs a crucial function to enhance energy effectivity, scale back measurement, and handle warmth extra successfully in energy conversion functions utilized in AI knowledge facilities, as an illustration. By collaboration with business consultants and with our superior testing options we allow our clients to develop dependable and environment friendly programs that meet the rigorous calls for of recent knowledge processing functions.”
