Abstract
The rectifier circuit includes: three terminals A, K, VR; voltage comparator including a positive input terminal, a negative input terminal, and a comparative output terminal; current switching unit including source terminal, drain terminal, and control terminal; first switching unit that conducts or cuts off between source terminal and control terminal of the current switching unit; second switching unit that conducts or cuts off between control terminal of the current switching unit and terminal VR; and reference voltage generator that uses terminal A and terminal VR as input terminals, and includes a voltage output terminal. The voltage output terminal of reference voltage generator is connected to the negative input terminal of the voltage comparator, terminal K is connected to the positive input terminal of voltage comparator, and current flow between first switching unit and second switching unit is exclusively allowed or interrupted by a signal output from the comparative output terminal of voltage comparator).
