Power Reception Device and Power Reception Control Method

A power reception control method comprising:

• receiving electric power transmitted from a power transmission coil with a power reception coil;
• rectifying alternating current power received by the power reception coil with a rectification circuit;
• detecting that a voltage applied to a load has become equal to or higher than a predetermined value with a control circuit connected between the rectification circuit and a load to which direct current power outputted from the rectification circuit is supplied;
• switching a switch connected between a positive electrode and a negative electrode of the load from a non-conducting state to a conducting state, while the power transmitted from the power transmission coil is being received by the power reception coil, when the voltage applied to the load has become equal to or higher than the predetermined value;
• and
• preventing a current from flowing from the positive electrode to the negative electrode through the switch with a rectification element connected between the positive electrode or the negative electrode and the switch.
