Abstract
Description
<電力伝送システムの構成>
図1は、本開示の実施の形態1に従う非接触送電装置が適用される電力伝送システムの全体構成図である。図1を参照して、この電力伝送システムは、送電装置10と、受電装置20とを備える。受電装置20は、たとえば、送電装置10から供給され蓄えられた電力を用いて走行可能な車両等に搭載される。
インバータ220の温度が上昇した場合に、送電電力を低下させることにより、インバータ220に流れる電流を低下させてインバータ220の発熱を抑え、インバータ220の温度を抑制することが考えられる。しかしながら、上記のような電力伝送システムにおいては、送電電力を低下させても、送電電力の低下に応じてインバータ220の温度が効果的に下がらない場合がある。
ここで、I1は送電部240に流れる電流を示し、I2は受電部310に流れる電流を示す。受電電力が一定であれば電流I2はほぼ一定となるので、電力伝送効率ηは、電流I1の2乗に反比例することが式(1)から分かる。したがって、送電部240に流れる電流Isが小さいほど電力伝送効率ηは高くなる。
実施の形態1では、インバータ220の温度Tinvが制限温度Tthを超える場合に、送電電力Psの大きさを維持しつつ、インバータ220の電流Iinvが減少する方向に周波数fを調整するものとした。
