A power supply device (S) is provided with: an inverter circuit (3); a resonant circuit (4) that is connected with the inverter circuit (3) and that transmits AC power toward a power-receiving device (R) using a non-contact method; and a switching control unit (7) that adjusts the parameters of each of switching signals that control the switching on and off of each of switching elements that constitute the inverter circuit (3) so that the inter-terminal voltage of specific elements that constitute the inverter circuit (3) or the resonant circuit (4) does not surpass a predetermined limit value.
