A Bench Built for Power Devices
Applying a power device correctly is as important as choosing the right part. To support customers more effectively, BeiLuo has opened an FAE verification bench dedicated to Silan IGBT, SiC MOSFET and IPM. The bench lets our engineers measure gate waveforms, switching loss, turn-off overshoot and thermal behavior before a customer commits to a design, turning advice into evidence.
What We Measure
The bench is equipped with high-bandwidth oscilloscopes, differential probes, current sensors and a thermal stage. Engineers characterize gate-drive behavior, measure turn-off overshoot at the device terminals, and quantify switching loss across frequency. For SiC MOSFETs, the bench highlights the fast-switching effects that make layout critical, and the four-lead package benefits are easy to demonstrate. For IPM, the bench verifies the control interface, the overcurrent trip level and the protection response so that a customer's controller behaves as expected.
From Selection to Validation
When a customer asks which device suits their application, our FAE team can now validate the recommendation on the bench. We compare silicon IGBTs against SiC MOSFETs, match an IPM to a compact drive, and evaluate a discrete against a module for a given operating point. The result is a design path backed by measured data, which reduces the risk of late-stage surprises.
Thermal Validation
Thermal design is often where designs fail. The bench measures case temperature under load, letting us verify heatsink sizing against the device's junction-to-case thermal resistance and the customer's ambient. For high-current modules and IPM with integrated protection, this validation is especially valuable, because a marginal thermal path can derate a design or trigger the thermal shutdown during normal operation.
Supporting Customers Remotely
Not every customer can send hardware, so the bench also produces reference data that our team shares directly: recommended gate-drive values, the expected overshoot and the thermal headroom for common configurations. This shortens customer bring-up and makes remote support concrete, because the customer receives numbers and waveforms rather than general advice.
Validation Reports
For larger projects we prepare short validation reports that summarize the measurements, the recommended component values and the thermal margin. These reports help customers justify a design decision internally and give their own review process a documented basis.
Why This Matters for Silan Designs
Silan's IGBT and SiC devices switch fast and reward a tight layout, and IPM modules move much of the power-stage engineering inside the package. Both benefit from measured guidance: the IGBT and SiC on gate drive and commutation-loop layout, and the IPM on the control interface and the trip level. Our bench targets exactly those decisions, so a customer's first prototype is closer to a production design.
Measuring the Integrated IPM
An intelligent power module hides much of its behavior inside the package, so the bench plays an especially useful role for IPM customers. Engineers verify the current-sense resistor value that sets the overcurrent trip level, confirm the protection response and measure case temperature under load. Because those characteristics depend on the customer's board and cooling, a bench measurement turns a datasheet parameter into a verified design value.
Consistent Method
Every measurement follows the same method, so results are comparable across devices and generations. That consistency lets us tell a customer, with evidence, how a SiC MOSFET compares with an IGBT at their operating point, rather than repeating a general claim.
A Commitment to Engineering Support
BeiLuo is an authorized Silan distributor, but we aim to be more than a source of parts. The verification bench is part of a deliberate investment in engineer-level support, because the customers who buy power devices also need help applying them. That support, combined with authorized stock and complete documentation, is what distinguishes a true distributor from a broker.
How to Use the Bench
Customers can request bench support through the contact page. Describe the application, the candidate device and the operating point, and our team will either provide reference data or, for larger projects, run a focused validation and share the results.
Looking Ahead
We plan to expand the bench's coverage to more device families and to standardize the reference data we publish, so customers can self-serve more of the common questions. The objective is consistent, measurable support that helps Silan designs reach production faster and perform reliably in the field.
