High spec bidirectional power supply simplifies EV powertrain testing

15-06-2020 | MDL | Automotive Technologies

The new MDL Technologies Chroma 62000D series of bidirectional DC power supplies is ideal for high current testing of EV powertrain components. The series offers two-quadrant operation with both programmable DC output and regenerative DC loading in a single unit.

High power components able to be tested include bidirectional on-board chargers, bidirectional DC converters and DC/AC motor drivers, as well as power conversion simulation tests of batteries in either direction.

Compliant with LV123 and LV148 standards for EV component testing, the series provides a very fast cross-quadrant bandwidth that provides a rapid transient response time as short as 1.5ms or less. A broad range of voltage and current combinations are offered in constant power mode, and constant current and constant voltage modes are also available.

Across the range, maximum power is provided from 6kW to 18kW, with an industry-leading power density of 18kW in a 3U rack height. Output current ratings are up to +/-540A, with voltage ratings up to 1800VDC. When greater power is needed, master/slave capability facilitates up to ten of the units to run in parallel to achieve up to 180kW.

"As well as offering market-leading performance, the compact but powerful 62000D is available at an affordable price," said MDL managing director Mark Lucock.
