摘要 |
In a first power transmission period, a power transmission device holds, in a memory, a value indicating a frequency f0 corresponding to an actual voltage value that matches a requested voltage value, then causes first AC power to be transmitted by using the frequency f0, and uses a foreign substance detector to determine whether or not a foreign substance is present. When it is determined that no foreign substance is present, in a second power transmission period, the power transmission device causes the power transmission of the first AC power to be resumed by using the value indicating the frequency f0, the value being held in the memory. |
