A Bench Built for Power Modules
Applying a power module correctly is as important as choosing the right part. To support customers more effectively, BeiLuo has opened an FAE verification bench dedicated to MacMic IGBT, FRD and SiC modules. 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 module terminals, and quantify switching loss across frequency. For SiC modules, the bench highlights the fast-switching effects that make layout critical. These measurements let us recommend gate resistors, dead time and snubbers with confidence rather than by rule of thumb.
From Selection to Validation
When a customer asks which module suits their application, our FAE team can now validate the recommendation on the bench. We compare HN and 6TC IGBT modules, match FRD diodes to the freewheeling path, and evaluate SiC against silicon for high-frequency stages. 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 module's junction-to-case thermal resistance and the customer's ambient. For high-current modules, this validation is especially valuable, because a marginal thermal path can derate a design severely.
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, expected overshoot and thermal headroom for common configurations. This shortens customer bring-up even when the board is far away, and it complements the application notes and selection guides our FAE team publishes.
How to Use It
If you are designing a motor drive, welder, solar inverter or SiC converter with MacMic modules, contact BeiLuo with your topology, voltage, current and switching frequency. We will recommend a module set, characterize it on the bench where useful, and provide gate-drive and thermal guidance alongside genuine modules and full documentation.
Turning Measurements Into Guidance
The bench is not an end in itself; it produces the reference data our customers use directly. When we recommend a gate resistor range or a dead-time setting, it is backed by measured waveforms rather than rules of thumb. When we say a module will run cool with a given heatsink, it rests on measured case temperature against the datasheet thermal resistance. This evidence-based approach shortens customer bring-up and reduces the risk of late-stage surprises in high-frequency power stages. The bench also lets us evaluate new MacMic releases, including SiC MOSFET modules, before they reach customer designs, so our advice stays current. Customers can request specific characterizations, such as switching energy over frequency or overshoot at a target current, and our engineers will measure them and share the results alongside a recommended implementation tailored to the application.
