Power reception device and power transmission device
Abstract:
A power reception device includes a power reception coil configured to couple with a power transmission coil included in a power transmission device; a rectifier circuit including a diode and a transistor electrically connected to the power reception coil and configured to rectify a high frequency AC current flowing in the power reception coil; outputs configured to output the current rectified by the rectifier circuit to a load; a voltage detection circuit configured to detect an output voltage Va; and a controller configured to control an operation of the transistor based on the output voltage Va. The controller turns off the transistor when the output voltage Va≤the threshold value Va1 is satisfied and causes the rectifier circuit to execute a rated rectification operation, and turns on the transistor when the voltage Va≥the threshold value Va2 is satisfied and stops the rated rectification operation.
