Streamlining Power Converter Support and Development with Marple at BrightLoop

‍

About BrightLoop

BrightLoop is a France-based company specializing in advanced power electronics. Their converters, used in DC-DC and AC-DC applications, are engineered for modularity—allowing customers to stack multiple units to meet high-power demands. As a company deeply invested in both hardware and embedded software development, they face complex engineering challenges that demand flexible, insightful data analysis.

The Challenge

Whether supporting customers in the field or validating new designs in the lab, BrightLoop handles high-frequency telemetry data across multiple units. Conventional tools couldn’t keep up. “In early setups where we had 10 to 12 converters stacked, the data load was overwhelming,” says Pierre Bouchet, Principal Engineer at BrightLoop. “We needed speed, clarity, and the ability to correlate data across units in real time.”

Why Marple

BrightLoop adopted Marple to improve both customer support and R&D workflows. The tool quickly became central to their data analysis stack for:

• Customer support: When customers first integrate BrightLoop converters into their systems, Marple helps the engineering team analyse logs and troubleshoot commissioning issues with speed and precision. The same is done during the lifetime of the converter.
• R&D insight: Marple allows engineers to explore and validate time-dependent phenomena during development—whether testing new features or diagnosing edge cases.
• Workflow integration: The flexible API lets them automate recurring tasks, such as data import and visualization setup, making analysis faster and more consistent.

What Stands Out

• Intuitive onboarding: Team members unfamiliar with Marple can join a workspace and get started in minutes. No training needed.
• Scalable analysis: With Marple, the team handles large volumes of time series data effortlessly, correlating signals across stacked units.
• Automation-ready: Their engineers use the API to integrate Marple into their scripting pipeline, making data prep and post-processing seamless.

The Impact

In a critical early deployment involving multiple converters, Marple proved essential. “That experience convinced us Marple wasn’t just useful—it was indispensable” Bouchet says. The ease of use, combined with advanced analysis capabilities, has made it a mainstay in BrightLoop’s engineering toolkit.

The Verdict

“Marple has become the obvious tool for anything related to time series analysis in our team. It fits naturally into how we work—and raises expectations for all our other tools.”
