Contactless Power Feeder

Multiple secondary units include a target unit including a switcher that switches between a first mode in which a synchronization signal input into an input unit is transmitted to a processor and output from the processor to an output unit and a second mode in which the synchronization signal input into the input unit is transmitted to the output unit without being through the processor. The switcher switches to the first mode when the processor is in operation and to the second mode when the processor is stopped.
