Abstract: A system (10) applied in switch tube for suppressing conducted EMI and a domestic appliance are provided, and the system (10) includes a conduction EMI suppression circuit, an inductive load (1, 71, 81) and at least one switch tube (2, 72, 82). The conducted EMI suppression circuit includes one inductor (3, 73, 83, 123) and an RC circuit (4, 74, 84, 124). The inductor (3, 73, 83, 123) and each switch tube (2, 72, 82) are connected in series. The inductive load (1, 71, 82) and each switch tube (2, 72, 82) are connected. The inductor (3, 73, 83, 123) are connected in series with each switch tube (2, 72, 82), and further connected in parallel with the RC circuit (4. 74, 84, 124). The conduction EMI suppression circuit is configured to suppress conducted EMI generated by each switch tube (2, 72, 82) being turned off.
