Abstract:
A rectification circuit comprising:a transistor and a control circuit connected to said transistor, wherein said transistor comprises a current path and a control terminal, receives a target voltage to be rectified at one end of said current path, and outputs a rectified voltage at the other end of said current path by being activated and inactivated in accordance with control of said control circuit, said control circuit is connected to said current path and said control terminal of said transistor, and controls a signal to be supplied to said control terminal, in accordance with the direction of a current flowing through a node between the one end of said current path and an external circuit, thereby activating or inactivating said transistor to make said transistor rectify said target voltage, wherein said transistor serves as an inverse transistor when it is turned on.
