PROBLEM TO BE SOLVED: To provide a power supply system capable of controlling partial charge of a power loss among a plurality of switching elements that form a power converter.SOLUTION: A power converter 50 includes a reactor L1 and switching elements S1-S4 configured to alternately form a first current path for storing energy in the reactor L1 and a second current path for emitting energy in the reactor L1 between a DC power source B1 and power lines PL and GL in response to a control signal from a control device 40. The switching elements S1-S4 include switching elements S3 and S4 which are electrically connected in series and configured to be commonly turned on and turned off in accordance with the control signal, thereby forming and cutting off the first current path. The control device 40 generates the control signal in such a manner that a time difference is provided in turn-on timing or turn-off timing between the switching elements S3 and S4.SELECTED DRAWING: Figure 1 |
