Chroma Battery Simulator – Leading Future Energy Development

Bidirectional DC-DC Converter Designated by IFEC as the Only Official Verification Tool

The IFEC 2018 (International Future Energy Challenge) sponsored by IEEE was held in Tsinghua University, Beijing. Ten teams from all over the world competed in the IFEC. The contest placed the top international students in power electronics and in the new energy generation field to compete. Chroma is the only officially designated test equipment provider for the IFEC and other sponsored competitions. For this year’s topic of “High-Efficiency and High Power Density Isolated Bidirectional DC-DC Converter for Residential Energy Storage Systems”, Chroma has tailored an automatic test system under the competition specifications.

The competitors must complete full charge and discharge efficiency tests, charge and discharge voltage ripples, overcurrent protections, and overcharge/undercharge test conditions. The Chroma 17020 Battery Simulator with built-in bidirectional DC power mode, independent multichannel design, high precision output and measurement specifications, DC input and output current switch without interruption, is suitable for testing the bidirectional DC-DC converters for incoming/outgoing shipment inspection and design verification, etc. Chroma, with innovative technical strength and expanding R&D resources to satisfy various front-end applications, was well prepared for the competition and earned high recognition from the committee.

During the IFEC 2018 finals, an international symposium “Future Power Electronics Technology” was also held for the first time to provide members a high-end communication platform. The speakers were formed by many renowned committee reviewers and IEEE associates. Being a leading company in the field of new energy solutions, Chroma shared in the R&D and testing of DC/DC converter test systems. This connected the industry development trends through practical and theoretical interactions and demonstrated Chroma’s long-term support and contributions in academia for fostering advanced talents.

Chroma Launches Its New 63000 Series DC Electronic Loads to Satisfy the Tests for Small Power Supplies and Batteries

Chroma 63000

To meet the testing requirements of small power supplies, Chroma has launched a brand new 63000 Series of benchtop DC electronic loads specifically designed for testing lower power adaptors, cell phone chargers, small batteries (such as cell phone batteries), D/D converters, USB PD, and so on. Different from the modular electronic load, they can be used without a mainframe. With the advantages of its compact size, lighter weight, low cost, and portability, the 63000 Series is the perfect electronic load for R&D labs and colleges.

 Chroma 63000

The voltage and current specifications of each model in the 63000 Series are comprised of three settings and three measurement ranges. For adapters and USB PD’s that require higher testing accuracy, small current test like 0.1A is often performed during efficiency testing. However, misjudgment frequently occurs due to insufficient range or low accuracy. The minimum setting and measurement current range of the 63004-150-60 is 2A and the current error is less than 2mA which makes it suitable for these tests and validating the regulatory compliance of Energy Star. The maximum current output of a single load is up to 60A, with power up to 350W. Besides, the large scaled fonts and moderate shortcuts in its 3.5” LCD display bring great usability in the forms of sight and touch.

In addition to the basic CC, CR, CP, CV, and CRD modes, the 63000 Series also has battery discharge, User Defined Waveforms (UDW), and programming functions to satisfy the test requirements for D/D converters, 3C battery dischargers, and switching power supplies.

The battery discharge mode is applicable for 3C battery discharge test and can record the Wh (Watt) and Ah (Ah) during battery discharge. The User Defined Waveform (Figure 1) can simulate the real load current allowing the R&D test engineer to verify the power in the actual load current. The quality assurance department can reproduce the actual load current situation to reduce the development and validation time. For other DC power and component applications such as fuel cells, fuses, switches, and wiring tests, the pulse current (Figure 2) function is provided to test them by setting the repeat time to 1 in the existing dynamic loading mode.
