Abstract

There is provided a boost converter capable of reducing internal pressure in elements without the employment of a separate snubber by clamping a voltage, transmitted to the elements, to a charging voltage or an output voltage during power conversion. The boost converter includes a transformer including a primary winding receiving input power and a secondary winding electromagnetically coupled to the primary winding and having a predetermined turns ratio therewith; a switching part allowing the input power transmitted to the primary winding to be on or off according to a predetermined switching duty; a clamping part including a link capacitor charged with the input power obtained when the switching part is switched on, and power transformed based on the predetermined turns ratio; and a stabilizing part stabilizing power outputted from the clamping part.

Description

[0001] This application claims priority to Korean Patent Application No. 10-2010-0077737 filed with the Korean Intellectual Property Office on Aug. 12, 2010, the disclosure of which is incorporated herein by reference. technical field [0002] The present invention relates to a boost converter, and more particularly, to a boost converter capable of converting power by transferring The voltage clamped to the charging voltage or output voltage to reduce the internal pressure of the component. Background technique [0003] In recent years, various power supply devices capable of boosting low DC voltages have been developed for electronic drive systems using fuel cells or storage batteries, semiconductor manufacturing equipment, large-scale display equipment, ultrasonic or X-ray equipment, and the like. [0004] For these power supplies, a boost converter can serve as a representative power supply. [0005] In a common boost converter, it is difficult to obtain a high boost rat...
