Satellites, hybrid electric vehicles (HEVs), uninterruptable power supplies (UPSs), alternate energy power sources, and a number of other modern power systems supply power when it is opportune. They rely on bidirectional and regenerative energy systems and devices for storage in order to provide a continuous supply of power on demand. When engineers test these devices in their system or product, they need a solution that can both source power and sink power to satisfy the bidirectional power capabilities of their unit under test. Read this application note to discover how to conquer the multi-kilowatt source/sink test challenge with the latest methodologies and test equipment.
