The present invention addresses the problem of providing a wireless power supply device and a wireless power supply system capable of preventing the loss of an inverter unit from increasing. The wireless power supply device (100) of the present invention is provided with an inverter unit (10), a control unit (11), and a power supply unit (12). The control unit (11) stops the switching operations of first switching elements (Q1, Q4) and second switching elements (Q2, Q3) when a first condition is satisfied during a pause period. The pause period is the time interval from a time point when the first switching elements (Q1, Q4) are brought from the on-state to the off-state to a time point when the second switching elements (Q2, Q3) start to change from the off-state to the on-state. The first condition is the state in which the voltage value of a voltage applied to at least one of the first switching elements (Q1, Q4) and the second switching elements (Q2, Q3) does not change to a first threshold value. |
