description	Embodiments of the present invention relate to the technical field of power electronics, and disclose a three-level converting circuit, and a starting method and electronic device thereof. The circuit includes: a first voltage source (V1); a first soft-start circuit (110); a first capacitor (C1); a first switch (S1), a second switch (S2), a third switch (S3), and a fourth switch (S4) sequentially connected in series; a flying capacitor (Cf); a second soft-start circuit (120); a second voltage source (V2) and a second capacitor (C2). The three-level converting circuit provided according to the embodiments of the present invention can pre-charge the flying capacitor (Cf), the first capacitor (C1), and the second capacitor (C2) when executing the starting method thereof, thereby preventing the over-voltage damage of the switches.
