As power electronics continue to evolve with the adoption of silicon carbide (SiC) and gallium nitride (GaN) semiconductors, engineers are facing increasing challenges in validating switching performance, insulation reliability, and converter efficiency. Faster switching speeds, higher operating voltages, and steeper voltage transients demand test equipment capable of accurately reproducing real-world operating conditions. SAXOGY Power Electronics has developed a portfolio of automated test benches and measurement systems designed to address these requirements across semiconductor characterization, inverter development, electric drives, and high-voltage insulation testing.
Rather than offering generic laboratory instruments, SAXOGY focuses on application-specific test systems that automate complex power electronics measurements. Its solutions support the development and validation of power semiconductors, gate drivers, converters, electric motors, and complete power electronic assemblies, enabling engineers to obtain highly repeatable measurement data while significantly reducing testing time.
One of the company's core technologies is its automated double-pulse test (DPT) bench, which is used to characterize the dynamic switching behavior of IGBTs, SiC MOSFETs, and GaN devices. Double-pulse testing is an industry-standard technique for evaluating switching losses, turn-on and turn-off behavior, reverse recovery characteristics, overshoot voltages, and electromagnetic oscillations under realistic operating conditions. While these tests have traditionally required extensive manual setup, SAXOGY's automated platform streamlines the entire process by automatically varying operating parameters such as DC-link voltage, load current, and gate driver settings. This enables comprehensive characterization across a wide operating range while improving repeatability and minimizing operator intervention.
The company also addresses one of the emerging reliability challenges associated with high-speed wide-bandgap power devices—insulation aging caused by extremely high dv/dt switching transients. Modern SiC-based inverters can generate voltage slew rates exceeding 100 kV/µs, placing significant electrical stress on motor windings, cable insulation, and packaging materials. To evaluate these effects, SAXOGY has developed a modular high-voltage dv/dt pulse generator test bench capable of generating adjustable bipolar voltage pulses with programmable amplitudes, frequencies, and rise times. The system reproduces the electrical stresses encountered in real inverter operation, allowing manufacturers to perform accelerated insulation endurance testing and study long-term degradation mechanisms.
A distinguishing feature of this platform is its transformerless modular topology, which enables scalable high-voltage pulse generation while maintaining efficient energy transfer between multiple stages. The architecture enables output voltages ranging from hundreds of volts to several kilovolts peak-to-peak and supports dynamic adjustment of voltage rise times via proprietary gate-driver technology. This flexibility enables researchers to investigate how different switching conditions influence insulation lifetime and dielectric performance across a wide range of applications, including electric motors, power modules, and semiconductor packaging.
Beyond semiconductor testing, SAXOGY's equipment supports the broader development of power electronic systems by integrating precision measurement hardware, programmable power stages, automated control software, and synchronized data acquisition into a unified platform. The automation capabilities allow engineers to execute extensive characterization campaigns with minimal manual intervention, improving development efficiency while generating consistent datasets for design optimization and reliability analysis.
The company's technology reflects a growing trend toward automated validation environments as the power electronics industry transitions to higher switching frequencies, increased power densities, and more stringent reliability requirements. By combining advanced power conversion expertise with purpose-built test equipment, SAXOGY enables manufacturers to validate semiconductor devices, inverter systems, and insulation technologies under conditions that closely replicate real-world operation, helping accelerate the development of next-generation electrification systems.
