<p>A transformer module (10) is mounted to a ground electrode pattern (40G) on a mounting substrate (40), and comprises a transformer (20) and an electrostatic shield (30). The transformer (20) comprises a magnetic core (22) forming an open magnetic circuit, and a primary winding and a secondary winding that are wound around the core (22). The electrostatic shield (30) covers the transformer (20), and shields the electric field radiated from the transformer (20). The electrostatic shield (30) is configured from a first metal member (31) and a second metal member (32). Slits (33, 34) for inhibiting the flow of eddy currents generated by leakage flux from the transformer (20) are provided in the first metal member (31) and the second metal member (32). As a result, a converter transformer, the transformer module, and a wireless power transmission system are provided that are capable of suppressing reduction in Q values, electrostatic shielding, and being more compact.</p> |
