This reference design is an isolated high-side current sensing design for a smart combiner box in a grounded or ungrounded system. The current sensing topology enables multichannel, sub ±1% error, isolated current sensing for high-voltage systems up to 1200-VDC, limited by the DC/DC transformer.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
