Power transmission control device, power transmission device, electronic instrument, and non-contact power transmission system

Abstract

A power transmission control device (20) provided in a power transmission device (10) of a non-contact power transmission system includes a drive clock signal generation circuit (25) that generates a drive clock signal that specifies a drive frequency of a primary coil (L1), a driver control circuit (26) that generates a driver control signal based on the drive clock signal and outputs the driver control signal to a transmission driver (12), a waveform adjusting circuit (32) that outputs a waveform adjusting signal of an induced voltage signal of the primary coil (L1), a pulse width detection circuit (33) that receives the waveform adjusting signal and the drive clock signal and detects pulse width information relating to the waveform adjusting signal, and a control circuit (22) that detects a change in secondary-side load (40) based on the detected pulse width information.
