Pre-Switch includes remote update and analysis features in Pre-Flex controller for SoC

Pre-Switch, a producer of AI-based so -switching power systems, has allowed the reprogramming of its Pre-Flex motor/inverter controller SoC for EVs, and has incorporated a digital oscilloscope, allowing designers to remotely diagnose and make modi cations.

Pre-Flex ICs have AI algorithms for so switching across all operating voltages, load situations and temperatures, and adjust cycle-by-cycle. Pre-Switch technology delivers 99.57% (peak) and 98.5% (at 5% load) inverter e ciency for e-mobility applications at 100 kHz switching frequency. Deep View, the integrated digital oscilloscope, allows 12 channels and 160 MSPS to analyze switching timing. Recording and exporting traces show system performance, helping in diagnosing issues and taking corrective action.

“Pre-Switch eliminates switching losses and thereby reduces the amount of SiC or IGBTs needed for high e ciency. is substantially improves low load e ciency and runs at 5-10 times higher switching frequencies which improves motor e ciency and reduces DC link capacitor size and cost,” said Bruce Renouard, PreSwitch’s CEO. “To enable engineers to utilize Pre-Flex AI technology, Pre-Switch developed the CleanWave inverter reference system, the PDS-2 development system with Deep View and the remote programming, Pre-Tune dynamometer motor control tuner, a resonant tank design tool and training courses.”

Huber’s new Unimotive model range offers precise temperature control for battery and material tests

Temperature control is a critical factor during stress and load testing in the development of batteries and other vehicle components. e heat transfer uid (HTF) used in testing is o en a water-ethylene glycol mixture.

To address these applications, thermoregulation specialist Huber has expanded its portfolio to include temperature-control systems designed and tested speci cally for use with water-ethylene glycol over the temperature range of -45° to 95° C for the automotive industry.

Based on Huber’s Unistat technology, which the company developed over 40 years ago, these systems operate with a very low volume of HTF, and feature plate heat exchangers and a sealed uid system. Huber says this results in very short “time to temperature” times, as well as extremely responsive, stable, accurate and repeatable temperature control.

e Unimotive series comprises ve units with up to 35 kW cooling capacity and 24 kW heating capacity. Each model is tted with a magnetically coupled, speed-controlled pump with a maximum ow of 145 l/ min and pressure up to 5.5 Bar.

Unimotive devices can be individually con gured and adapted to various test situations, or integrated into existing test benches. Various sensors, expansion vessels, pumps and data interfaces are available as accessories.

Huber can build custom-designed solutions for demanding applications, for example those requiring high pressures or aggressive uids.

All Unimotive models are operated using a touchscreen controller that supports the most common data communication protocols (including Pro bus, Modbus, TCP, Ethernet, OPC-UA, RS232 and USB), enabling easy integration into automated industrial environments.
