A wireless power receiving circuit (100) constitutes a wireless power receiving apparatus with a power receiving coil (102). A capacitor (C1) is connected to the internal power supply line (120), and a secondary battery (2) is connected to an output line (122). An H-bridge circuit (104) includes transistors (MH1, MH2, ML1, ML2), which are N-channel MOSFETs. A first switch (SW1) is provided between a rectifying line (124) and the internal power supply line (120). A second switch (SW2) is provided between the rectifying line (124) and the output line (122). A voltage (VDD) of the internal power supply line (120) is supplied to the power supply terminal (108) of a controller (106). |
