Title:
RECTIFIER AND NON-CONTACT POWER-FEEDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/189300
Kind Code:
A1
Abstract:
This rectifier comprises a power feeder for supplying alternating current, a first switching element in which a switch is made between a conduction state and a non-conduction state with respect to the alternating current, a detection circuit which is connected in series to the first switching element and to which an AC voltage that corresponds to the alternating current is applied, and a control circuit for switching between the conduction state and the non-conduction state of the first switching element on the basis of the AC voltage. Chattering occurring in a switching element is thereby suppressed while an increase in power consumption is limited.
