The power converter has a primary winding and a secondary winding isolated from each other. The secondary winding can de-energize to provide the output voltage at an output node for powering a load. The winding voltage at across the secondary winding is sensed to provide a non-switching time, which is checked if it exceeds a predetermined reference time. The output voltage is compared with a predetermined voltage. A discharge current is provided as the dummy load to drain from the output node and to lower the output voltage if the on-switching time exceeds the predetermined reference time and the output voltage exceeds the predetermined voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dummy load controllers and control methods for power supplies capable of quickly lowering output voltage at output node","description":"A power converter provides a dummy load to lower an output voltage under a light-load or no-load condition.
