SECONDARY-SIDE POWER RECEIVING CIRCUIT OF NONCONTACT POWER SUPPLYING EQUIPMENT

Title:

SECONDARY-SIDE POWER RECEIVING CIRCUIT OF NONCONTACT POWER SUPPLYING EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2006/115196

Kind Code:

A1

Abstract:

There are provided a plurality of pickup coils (2A,2B), to which resonance capacitors (3A,3B) are series-connected to form resonance circuits (4A,4B), respectively, which resonate with a frequency of an inductive path (1). The resonance circuits (4A,4B) are series-connected to each other and further provided with rectifier circuits (6A,6B), respectively, which rectify the voltages generated by the resonance circuits (4A,4B). The rectifier circuits (6A,6B) are parallel-connected to each other to supply a power to a load (10). A switch (5) is provided which connects or disconnects the resonance circuits (4A,4B). A voltage controller (11) is also provided which controls the switch (5) so as to control the output voltage to be applied to the load (10).
