Diode Detector Inputting Power circuit

Published:2011/5/9 22:10:00 Author:Sharon | Keyword: Diode Detector, Inputting Power

Diode detector inputting power circuit is shown in the figure. This is a simple half-wave rectifier and filter circuit. The circuit's total input resistance is 50Ω.VDis the rectifier, and Cis the filter capacitor. Input power PIN is rectified and filtered to output voltage Uo. The relation curve of Uo and the PIN at different ambient temperatures is shown below. The figure shows that only under the ambient temperature of +25 oC, Uo is approximately in linear relationship with the PIN; when the ambient temperature increases or decreases, Uo will reduce significantly.   (View)
