The dimming circuit includes a signal conversion circuit for converting an input signal to a sine-wave voltage signal and output the sine-wave voltage signal to a current sampling end of a power factor correction circuit. The dimming circuit also includes the power factor correction circuit to receive the sine-wave voltage signal for correcting power factor. A biasing current is generated according to the input signal and is positively correlated to the input signal, and a sine-wave current signal corresponding to the sine-wave voltage signal is a sum of the biasing current and a primary current of a transformer in the power factor correction circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dimming circuit and dimming system suitable for SCR dimmer circuit","description":"The present disclosure provides a dimming circuit for SCR dimmer (silicon-controlled rectifier) circuit.
