Bidirectional, Regenerative Sources and Loads

Many types of modern electrical devices recycle power back to the grid or must sink and source current for a variety of applications. Using regenerative AC & DC sources and loads allows for realistic test scenarios and a more efficient testing process. For example, Electric Vehicle bidirectional dc-dc converters and on-board chargers (OBC) sink and source current to the battery when charging/discharging or for regenerative breaking . Bidirectional sources allow these devices to be tested without the need for cumbersome test setups, batteries or multiple conventional sources. And with advanced software these test setups can be converted to closed-loop hardware-in-the-loop simulations which produce real-time test results.

So why adopt this technology? Both Bidirectional and regenerative AC and DC sources and loads can more closely simulate real-word operating environments, reduce the number of instruments needed in your test lab, and reduce energy usage over traditional test equipment which can only discharge power in the form of heat. When used widely in high power applications, this testing equipment will save electricity costs and reduce carbon footprints around the globe.
