Title:
ZERO-OUTPUT RIPPLE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2019/205740
Kind Code:
A1
Abstract:
A zero-output ripple converter; the magnetic core shape of a transformer is changed in that a magnetic column is added on the basis of an original converter structure, and a three-magnetic column magnetic core is changed into a four-magnetic column magnetic core. Then, a winding is added onto the added magnetic column, and a suitable voltage is added in the winding, such that magnetic flux generated by the added voltage offsets the influence that original magnetic flux has on output current ripples, and zero-output ripples is thus achieved. The present converter overcomes the defects of existing switch converters, and when an input voltage range is relatively wide, zero-output ripples may be achieved within the full input voltage range.
