In relation to selection of Schottky barrier diodes for diode rectification, apart from the reduction in efficiency, does the voltage drop by the amount of the forward voltage
1. affect the value of the preset output voltage? or,
2. affect the out ripple voltage?
3. Also, is the diode junction capacitance related to DC/DC operation?"
- The set value for the output voltage is the voltage after switching and smoothing with an LC filter, that is, the voltage fed to the load is generally fed back, and is regulated at the preset voltage, including the voltage drop due to the diode, and so there is no effect on the set value for the output voltage. There is also no effect on the output ripple voltage. The junction capacitance also is generally hardly affected at all.
