Patent abstract

A one way conductor includes a MOSFET and a driving device. The MOSFET has a source and a drain respectively serving a positive end P and a negative end N of the one way conductor. The driving device including a BJT differential amplifier detects a voltage difference between the source and the drain of the MOSFET. When the voltage of the positive end P is higher than the voltage of the negative end N, the driving device outputs a driving voltage to a gate of the MOSFET to turn on the MOSFET. If the voltage of the positive end P is lower than the voltage of the negative end N, the driving device cannot output the driving voltage for turning on the MOSFET, and the one way conductor is turned off at this time. Consequently, the one way conductor of the invention has the one way conductive property.
