Title:
CONTACTLESS POWER TRANSFER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/099169
Kind Code:
A1
Abstract:
A half-bridge inverter (20) is used as a high-frequency alternating-current power supply to be connected to the primary side of a contactless power transformer (30), and a voltage-doubler rectifier (40) is used for converting an alternating-current output from the secondary side of the contactless power transformer (30) into a direct current. Although the alternating-current output voltage of the half-bridge inverter drops to a half of that of a full-bridge inverter, because the output voltage of the voltage-doubler rectifier becomes two times as high as that of a full-wave rectifier, the voltage ratio between the input voltage to the inverter and the secondary-side direct-current voltage becomes almost the same as a whole. The voltage of the contactless power transformer (30) drops to approximately a half of the conventional voltage, which is advantageous in terms of insulation and reducing ferrite loss.
