Abstract: An abnormality judgment apparatus provided with a processing part, a communicating part able to communicate with a mobile object provided with a power reception apparatus receiving power wirelessly transmitted from a power transmission apparatus installed on a road, and a storage part storing power reception history information received from the mobile object. The processing part calculates a probability of occurrence of an abnormality in the power reception apparatus of the mobile object based on the power reception history information and detects a presence of an abnormality occurring location where the power transfer efficiency becomes less than a predetermined value and judges that an abnormality has occurred in the power transmission apparatus installed at the abnormality occurring location when an abnormality occurring location is detected and the probability becomes less than a predetermined judgment threshold value.

Abstract: A power supply apparatus may include an electronic control unit. The electronic control unit may be configured to set target timing of switching of each of the switch. The electronic control unit may be configured to set the target timing in one cycle of a first carrier wave in accordance with first timing and in one cycle of a second carrier wave in accordance with second timing. The first timing may be two of timing in the one cycle of the first carrier wave that are defined by a first target duty ratio and the first carrier wave. The second timing may be two of timing in the one cycle of the second carrier wave that are defined by a second target duty ratio and the second carrier wave. The second carrier wave may be in the same cycle as the first carrier wave.
Abstract translation: 电源装置可以包括电子控制单元。 电子控制单元可以被配置为设置每个开关的切换的目标定时。 电子控制单元可以被配置为根据第二定时根据第一定时和第二载波的一个周期来设置第一载波的一个周期中的目标定时。 第一定时可以是由第一目标占空比和第一载波限定的第一载波的一个周期中的两个定时。 第二定时可以是由第二目标占空比和第二载波限定的第二载波的一个周期中的两个定时。 第二载波可以与第一载波处于相同的周期。
