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 NCE Power SGT MOSFETs, Super Junction MOSFETs and Trench FS IGBTs. 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 for MOSFETs and IGBTs, measure turn-off overshoot at the device terminals, and quantify switching loss across frequency. For the Super Junction family, the bench highlights the enhanced body-diode recovery in a bridge stage. For an IGBT, the bench verifies the gate drive and the short-circuit withstand under a controlled fault.

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 an SGT MOSFET against a Super Junction MOSFET, match an IGBT to a high-current stage, and evaluate the freewheeling path 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 and PCB thermal design against the device's junction-to-case thermal resistance and the customer's ambient. For a surface-mount part, the bench confirms how much the PCB copper contributes to the thermal path.

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 NCE Power Designs

NCE Power devices span three families with different behavior, so measured guidance is especially valuable. An SGT MOSFET and a Super Junction MOSFET switch in different frequency bands, the Super Junction body diode matters in bridge converters, and an IGBT needs the right gate drive and dead time. Our bench targets exactly those decisions, so a customer's first prototype is closer to a production design.

Measuring the IGBT

An IGBT behaves differently from a MOSFET, so the bench plays a specific role for high-power customers. Engineers verify the gate drive and dead time, measure turn-off overshoot at the device terminals, and confirm the short-circuit withstand under a controlled fault. Because an IGBT bridge often uses a matched freewheeling diode, the bench also evaluates the diode pairing and its recovery behavior.

Consistent Method

Every measurement follows the same method, so results are comparable across devices and families. That consistency lets us tell a customer, with evidence, how two options perform at their operating point, rather than repeating a general claim.

A Commitment to Engineering Support

BeiLuo is an authorized NCE Power 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 NCE Power designs reach production faster and perform reliably in the field.
