Ideale Diode Schaltung. The two terminals of an ideal diode are called the anode and cathode where anode is positive and cathode is negative. Whereas if the diode is reversed biased it acts as an open switch as shown in the figure below.
When voltage is applied in reverse the diode conducts no current at all. Ideale diode mit stromspiegel. Sie hat in durchlassrichtung eine flussspannung unter 100mv wenn die ausgangsspannung über der schwellenspannung des mosfet liegt.
It is important to know that not to combine the connections on a diode up.
Eine ideale diode mit stromspiegel ist leider auch nur fast ideal. Die schaltung in bild 4 kommt einer idealen diode sehr nahe. To minimize this forward drop you can configure a mosfet as an ideal diode which has a very low drop in the forward direction equal to the current times the mosfet s on resistance while blocking the current in the reverse direction. An ideal diode is a diode that acts like a perfect conductor when voltage is applied forward biased and like a perfect insulator when voltage is applied reverse biased.
