Title:
WIRELESS POWER TRANSMISSION AND RECEPTION SYSTEM, POWER CONVERSION APPARATUS PROVIDED WITH SAME, AND POWER CONVERSION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/175319
Kind Code:
A1
Abstract:
Provided is a power conversion apparatus (1) that is able to prevent short-circuiting of inverter MOS transistors (13a-13d) included in an inverter (5). The power conversion apparatus (1) is provided with: a DC/DC converter unit (4) that converts the voltage of inputted DC power; a transformation unit (11) that transforms the DC power converted by the DC/DC converter unit (4); the inverter unit (5) that converts, into AC power, the DC power transformed by the transformation unit (11); a control unit (6) that performs drive control on the inverter unit (5); a wireless power reception unit (3) that receives power supplied by means of wireless power feeding and supplies the power to the control unit (6); a wireless power transmission unit (2) that transmits the power to the wireless power reception unit (3); and a power supply unit (41) that supplies the power to the wireless power transmission unit (2).
