POWER TRANSMISSION CONTROL DEVICE, NON-CONTACT POWER TRANSMISSION SYSTEM, POWER TRANSMITTING DEVICE, ELECTRONIC INSTRUMENT, AND WAVEFORM MONITOR CIRCUIT |
摘要 |
A power transmission control device includes a power-transmitting-side control circuit that controls an operation of a power transmitting device, a driver control circuit that controls operations of a first power transmitting driver and a second power transmitting driver, and a waveform detection circuit that performs a waveform detection process based on a monitor signal from a waveform monitor circuit. The first power transmitting driver drives a first node of a primary coil directly, and the second power transmitting driver drives a second node of the primary coil through a capacitor. A switch circuit is provided in the waveform monitor circuit, the switch circuit being situated in a signal path between the primary coil and a low-level power supply potential. The power-transmitting-side control circuit causes the switch circuit to be turned ON/OFF using a switch control signal.
