Diode circuit with ideal diode characteristic curve

摘要

The circuit includes a diode (7) and a power MOSFET (1) connected in parallel, using the control path of the power MOSFET. The load path forms the connection of an ideal diode. The gate connection of the power MOSFET has a predetermined voltage potential, and enables the MOSFET to be controlled in the flow direction of the diode, and to be isolated in the high resistance direction. Preferably, a Zener diode (6) is connected between gate (5) of the power MOSFET and the diode. A resistance is coupled between the power supply source (4) and the gate of the power MOSFET.
