Abstract: A planar transformer (2B) is applied to an isolated converter (400), and the isolated converter (400) includes a primary-side circuit (1B) and a secondary-side circuit (3B). The planar transformer (2B) includes a circuit board (CB2) and an iron core (C2), and the circuit board (CB2) includes a primary-side layer (LP) and a secondary-side layer (LS). The circuit board (CB2) is arranged in the isolated converter (400), and the primary-side layer (LP) and the secondary-side layer (LS) include a primary-side trace (Tp2) and a secondary-side trace (Ts2) respectively. The primary-side trace (Tp2) is formed on the primary-side layer (LP) and serves as a primary-side coil (22B) coupled to the primary-side circuit (1B). The secondary-side trace (Ts2) is formed on the secondary-side layer (LS) and serves as a secondary-side coil (24B) coupled to the secondary-side circuit (3B). The iron core (C2) includes a core pillar (C22), the core pillar (C22) penetrates a through hole (H4) of the circuit board (CB2), and the primary-side trace (Tp2) and the secondary-side trace (Ts2) surround the through hole (H4).
