Improvements in or relating to d.c. converters. |
摘要 |
A d.c. converter produces a d.c. output voltage from a lower d.c. input voltage by chopping the input voltage with a switch. A snubbing capacitor is connected across the switch to prevent damage to the switch when it changes from a conductive state to a non-conductive state. The energy diverted to the snubbing capacitor is fed to the output terminals of the converter in a two stage process. It is first transferred to a storage capacitor which together with the snubbing capacitor forms a resonant circuit. The energy is subsequently transferred to the output terminal when the voltage developed across the switch increases to the extent necessary to forward bias a diode which discharges the storage capacitor.
