Overview

One workflow, 146 test points.

Modern power electronics demand rigorous, repeatable validation to guarantee inverter reliability, efficiency, and compliance. The Automated Inverter Test Rig turns what traditionally required hours of manual bench work into a single, error-resistant LabVIEW workflow.

The rig is built around a modular LabVIEW state-machine test sequencer that checks 146 parameters — spanning DC/AC voltage and frequency, efficiency and THD, protection thresholds, and transfer-time analysis — guiding the operator through each step with prompts and automated pass/fail decisions. High-speed PXI and CompactDAQ data acquisition samples at up to 1 MS/s, capturing microsecond transients that a manual bench would miss entirely.

One hundred and forty-six tests. One sequencer. One pass/fail call.

Adaptive 4–20 mA-driven load control switches the bench from no-load to full-load, across resistive, inductive and capacitive modes, without any rewiring. Role-based user management with encryption, permissions and audit logs, plus automated calibration tracking against ISO 17025 practice, keeps every result traceable and every operator accountable.

Results export as PDF, CSV and XML with graphs, waveforms and full traceability, and can be auto-emailed to QA managers — turning a manual test log into a searchable, audit-ready record for manufacturing QA/QC, R&D characterization, field service, and certification and compliance work.

Architecture

In Depth

The complete technical read.

Engineering narrative for test engineers, QA managers, and procurement teams weighing an automated inverter bench against manual testing.

Introduction

Modern power electronics demand rigorous, repeatable validation to guarantee inverter reliability, efficiency, and compliance with industry standards. The Automated Inverter Test Rig delivers a turnkey solution that streamlines 146 distinct tests — spanning DC/AC performance, protection thresholds, dynamic response, and power quality metrics — into a single, tightly orchestrated LabVIEW workflow. By leveraging graphical "G" programming, integrated NI hardware, and SQL-backed data management, the system transforms what traditionally required hours of manual intervention into a rapid, error-resistant process.

Principle of operation

The test bench operates via a LabVIEW state-machine: initialization (self-tests and calibration checks), parameter sequencing (instrument settings, data capture, limit validation), operator interaction (setup prompts), error handling (fault detection and retries), and automated report generation (a PDF summary with graphs). Every stage runs against limit tables that can be edited by model or serial number, so a new inverter variant can be brought onto the bench without recompiling any software.

Software interface

Dashboard: real-time KPIs and calibration alerts.
Test Console: live waveform plots and operator controls.
Configuration Panel: editable test sequences and limit tables.
Report Manager: search, bulk export, and auto-email setup.
Remote Access: secure web-based status and report viewer.

Calibration & maintenance

The instrument registry is auto-imported from NI MAX, tracking serials and calibration dates for every connected instrument. An alarm engine issues email and pop-up alerts seven days before a calibration is due, and maintenance logs capture completed tasks with attached certificates. A service mode allows scheduled maintenance with full audit logging, so the calibration record stays continuous even during instrument servicing.

Conclusion

By consolidating manual procedures into an automated, LabVIEW-centric framework, the Automated Inverter Test Rig achieves consistent, standards-referenced results while drastically reducing test times. This translates to improved manufacturing yield, accelerated R&D cycles, and faster certification turnaround, delivering clear ROI across power-electronics applications.
