The problem to be solved by the present invention is to provide a power supply system and a moving object capable of reducing switching loss and steady-state loss compared with the prior art. In order to solve the problem, a power supply system (1) is provided with: a variable voltage power supply (7) that outputs power of a variable voltage from secondary-side input/output terminal pairs (72p, 72n); and a first power line (21) and a second power line (22) that connect the secondary-side input/output terminal pair (72p, 72n) and a load (4). The first power line 21 is provided with a first switching unit 31 and a third power line 23 connecting both ends of the first switching unit 31, and the third power line 23 is provided with a third switching unit 33, a DC power source 30, and a second switching unit 32 in series. A fourth power line 24 connects the third power line 23 and the second power line 22. The fourth power line (24) is provided with a fourth diode (34a) that allows the output current of the DC power supply (30) and blocks the reverse current thereof.
本发明要解决的问题是,提供一种与以往相比可以降低开关损耗及稳态损耗的电源系统及移动体。为了解决上述问题,电源系统1包括:可变电压电源7,从二次侧输入/输出端子对72p,72n输出可变电压的电力;及,第一电力线21及第二电力线22,连接二次侧输入/输出端子对72p,72n与负载4。在第一电力线21上设置第一开关单元31、及连接该第一开关单元31的两端的第三电力线23,在第三电力线23上串联设置第三开关单元33、直流电源30及第二开关单元32。第四电力线24连接第三电力线23与第二电力线22。在第四电力线24上设置第四二极管34a,所述第四二极管34a容许直流电源30的输出电流且阻断其逆向的电流。
