Ideale Diode Schaltung. An ideal diode also acts as a switch when the diode is forward biased it acts like a closed switch as shown in the figure below. According to the invention a power mosfet 1 with its control path is connected in parallel to the diode 7 and the load path of the power mosfet 1 forms the connection terminals of the ideal diode the gate connection of the power mosfet 1 is.
So when positive voltage is applied across the anode to the cathode the diode conducts forward current instantly. Below is the ltspice simulation of a simple ideal diode mosfet circuit. According to the invention a power mosfet 1 with its control path is connected in parallel to the diode 7 and the load path of the power mosfet 1 forms the connection terminals of the ideal diode the gate connection of the power mosfet 1 is.
Die schaltung in bild 4 kommt einer idealen diode sehr nahe.
Whereas if the diode is reversed biased it acts as an open switch as shown in the figure below. Eine ideale diode mit stromspiegel ist leider auch nur fast ideal. So when positive voltage is applied across the anode to the cathode the diode conducts forward current instantly. The v i characteristics of the ideal diode are shown in the figure below.
