System and method to regulate primary side current using an event driven architecture in LED circuit
Patent number: 10349482Abstract: The present invention discloses system and method to regulate primary side current using an event driven architecture in LED circuit. The system (100) performs a primary side regulation (PSR) of isolated or non-isolated LED driver topology such as fly back system. The primary side peak voltage or current is regulated to achieve desired secondary side currents without the need of additional external components. The architecture combines firmware and hardware to realize PSR. The method (200) effectively combines input wave shaping (Active PFC), dimming and PSR to achieve accurate secondary side currents. The method (200) corrects the Peak Regulation Voltage or current (PRV) of primary loop to meet desired half cycle reference voltage or current, which in turn achieves the desired secondary loop current in LED circuit.Type: GrantFiled: November 29, 2015Date of Patent: July 9, 2019Assignee: GLOBALFOUNDRIES Inc.Inventors: Abhisek Khare, Somnath Samantha, Krishnadas Bhagwat, Sumon K Bose, Hrishikesh Bhagwat, Rajesh Swaminathan, Ramesh G Karpur -
