Charger

A charger is configured such that switching control of a DC/DC converter (120) includes a first mode and a second mode, when switching from a first mode to a second mode, a dead time is set between the first mode and the second mode, and a first switch (S31) of a power fluctuation absorption circuit (130) is controlled to be in an off state during a time after the start of the dead time until a predetermined time expires. Wherein, in a first mode, at least one of the switches (S21-S28) of the DC/DC converter (120) is turned on, at least one of the switches (S21-S28) of the DC/DC converter (120) is turned off, and a first switch (S31) of the power fluctuation absorption circuit (130) is turned off, and wherein, in a second mode, the switch of the DC/DC converter (120) turned off in the first mode is turned on, and the first switch (S31) of the power fluctuation absorption circuit (130) is turned on. 一种充电器被配置为使得在DC/DC转换器(120)的切换控制包括第一模式和第二模式的情况下，当从第一模式切换到第二模式时在第一模式与第二模式之间设置死区时间并且电力波动吸收电路(130)的第一开关(S31)被控制为在死区时间
