Chroma 62000D programmable bidirectional DC power supplies have both power source and load characteristics, two quadrant operation, and allows feedback of the power from the DUT. They can be used for testing renewable energy power systems including PV/storage hybrid inverters, power conversion system (PCS) on charging/discharging, and as a battery simulator.
The 62000D also is a fit for testing power components used in electric vehicles, such as bidirectional on-board chargers (BOBC), bidirectional DC convertors, and DC-AC motor drivers, and power conversion simulation tests of batteries in both directions.
Power Conversion Testing of Bidirectional EV Components and Microgrid Storage
Renewable energy sources such as PV, EV, fuel cell, and battery are the market trend as the replacement of traditional energy sources (coal, oil, etc.). Yet, the subsequent rising need for electricity will actuate the faster commercialization of distributed energy storage in microgrids. The bidirectional design of power conversion devices urges battery applications to achieve high efficiency, high voltage conversion, and high power density direction, which prompts the need for battery simulation (bidirectional power supply) testing designs.
2-in-1: Bidirectional DC Power Supply and Regenerative Load
Chroma 62000D has a bidirectional switch power supply design that offers two-quadrant operation with positive current/positive voltage as well as negative current/positive voltage, enabling both DC power supply output and regenerative DC load. The absorbed energy feeds back to the grid with a conversion efficiency up to 93% and can operate in constant voltage, constant current, and constant power modes. Compared to traditional power supply and load, the 62000D two-in-one bidirectional DC power supply saves space, reduces energy loss and heat dissipation, and is easier to wire and configure.
