摘要： A power transmission device of a non-contact power transmission system includes a waveform monitoring circuit that generates and outputs a waveform-monitoring induced voltage signal based on a coil end signal of a primary coil, and a power transmission control device that controls a power transmission driver that drives the primary coil, the power transmission control device receiving the waveform-monitoring induced voltage signal and detecting a change in waveform of the induced voltage signal to detect a power-reception-side load state. The waveform monitoring circuit includes a first rectifier circuit having a limiter function, the first rectifier circuit including a current-limiting resistor provided between a coil end node where the coil end signal of the primary coil is generated and a monitoring node where the waveform-monitoring induced voltage signal is generated, performing a limiter operation that clamps the induced voltage signal at a high-potential-side power supply voltage, and subjecting the induced voltage signal to half-wave rectification.

摘要： A power transmission control device provided in a power transmission device of a non-contact power transmission system includes a drive clock signal generation circuit that generates a drive clock signal specifying a drive frequency of a primary coil, a driver control circuit that generates a driver control signal based on the drive clock signal, and outputs the driver control signal to a transmission driver, a waveform detection circuit that detects a change in waveform of an induced voltage signal of the primary coil, and a control circuit that performs foreign object detection based on a detection result of the waveform detection circuit. The drive clock signal generation circuit outputs the drive clock signal set at a foreign object detection frequency during foreign object detection, the foreign object detection frequency being a frequency differing from a normal power transmission frequency.

摘要： A power transmission control device provided in a power transmission device of a non-contact power transmission system includes a drive clock signal generation circuit that generates a drive clock signal, a driver control circuit that generates a driver control signal based on the drive clock signal, a waveform detection circuit, and a control circuit. The waveform detection circuit includes a pulse width detection circuit that measures a first pulse width period to detect first pulse width information, the first pulse width period being a period between a first edge timing of the drive clock signal and a first timing, the first timing being a timing when a first induced voltage signal that has changed from a low-potential-side power supply voltage exceeds a first threshold voltage. The control circuit detects the power-reception-side load state based on the first pulse width information.
