Title:
SWITCHING POWER CONVERTER USING COUNTER ELECTROMOTIVE FORCE
Document Type and Number:
WIPO Patent Application WO/2012/020921
Kind Code:
A2
Abstract:
The present invention pertains to a switching power converter using a counter electromotive force, which comprises: a switching power supply section operated by an on / off switch to supply power in the forward direction; a first power generating section having a first winding wire, which has one end connected to the switching power supply section and the other end connected to the ground portion to pass the power in the forward direction, and a second winding wire for outputting the first power which is induced by the power in the forward direction that is introduced into the first winding wire; a second power generating section connected to the first power generating section, and supplied with power in the reverse direction that is generated by the power in the forward direction, to output the second power which is induced by the power in the reverse direction; a power cutoff section interposed in the power supply line of the switching power supply section for cutting off the power in the reverse direction which is introduced into the switching power supply section; and a power separation section for cutting off the power in the forward direction with respect to the second power generating section. Accordingly, the counter electromotive force generated by a current in the forward direction that is supplied for power generation is detoured to another power generating circuit to generate additional power. Therefore, it is possible to improve power efficiency, and to minimize the design by removing elements for blocking heat, electromagnetic waves, noise or the like caused by the electromotive force.
