碩士 === 淡江大學 === 電機工程學系碩士在職專班 === 102 === This work proposes to develop an automatic compensation device for power diode output. This device uses an analog-to-digital converter to detect the forward voltage (VF) as the index address for the non-volatile memory, which stores the pre-calibrated digital current data of the power diode, to get the corresponding digital current. The read digital current is then converted to an analog current by the digital-to-analog converter to feed to the current control circuit of the power diode. This mechanism can control the output of the power diode to an almost constant level. The use of the output of the analog-to-digital converter as the index address of the non-volatile memory does not need an extra time for indexing, and it can increase the efficiency of the calibration significantly.
