High voltage boost converter for capacitor charging power supply

摘要

One of the essential parts in flash lamp pumped solid-state pulse laser is its Capacitor Charging Power Supply (CCPS). The aim of this project is to develop dc-dc converter or power supply for charging the capacitor. In this attempt, switch mode power supply technique adopted dc-dc boost converter was employed. The converter used 12 V dc power supply as an input voltage and serial of three capacitors with capacitance of 470 ?F and voltage rated of 450 V. The results obtained indicate that the developed converter was able to charge capacitor banks within 10 s and capable to convert variable output voltage in the range of 300-1000 V.
