To provide a contactless power supply device that reduces loss in a power supply coil and allows a feeder cable to be omitted.SOLUTION: A contactless power supply device SD1 has M (M is an integer equal to or greater than 5) coil units UN each forming 2N turns (N is an integer equal to or greater than 1) of loop coils CL1. Each of the M coil units UN includes 2N conductors CN1, 2N conductors CN2, and a connection switching unit SU1 that switches connections of the 2N conductors CN1 and the 2N conductors CN2. The connection switching unit SU1 switches between a state ST1 in which a loop coil CL1 is formed by the 2N conductors CN1 and the 2N conductors CN2, and a state ST2 in which a power supply line FD1 is formed by one set of N conductors CN1 and N conductors CN2 and a power supply line FD2 is formed by the other set of N conductors CN1 and N conductors CN2.SELECTED DRAWING: Figure 1
【課題】給電コイルの損失を低減させ、フィーダーケーブルを省略することができる非接触給電装置を提供する。【解決手段】非接触給電装置SD1は、2Nターン(Nは1以上の整数)のループコイルCL1をそれぞれ形成するM個(Mは5以上の整数)のコイルユニットUNを備える。M個のコイルユニットUNの各々は、2N本の導線CN1と、2N本の導線CN2と、2N本の導線CN1及び2N本の導線CN2の接続を切り替える接続切替部SU1と、を有する。接続切替部SU1は、2N本の導線CN1及び2N本の導線CN2によりループコイルCL1が形成される状態ST1と、一方のN本の導線CN1及びN本の導線CN2により給電線FD1が形成され、他方のN本の導線CN1及びN本の導線CN2により給電線FD2が形成される状態ST2と、を切り替える。【選択図】図1
