The converter is configured to output a load current signal according to a controlling signal. The load circuit is driven by the load current signal. The controller is configured to generate the control signal. The controller includes an error calculation unit, a regulation unit, a feed forward compensation unit, and an addition unit. The error calculation unit is configured to generate a first error signal according to a reference current signal and a feedback signal. The regulation unit is configured to generate a regulating signal according to the error signal. The feed forward compensation unit is configured to generate a feed forward compensation signal according to the reference current signal. The addition unit is configured to generate the control signal according to the regulation signal and the feed forward compensation signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light regulating apparatus with feed forward compensation and light regulating method thereof","description":"A light regulating apparatus includes a converter, a load circuit, and a controller.
