Title:
BOOST DC-TO-DC CONVERTER AND POWER CONVERTER POWERED BY THE SAME
Document Type and Number:
WIPO Patent Application WO/2011/092774
Kind Code:
A9
Abstract:
An object of the invention is to provide a boost DC-to-DC converter capable of changing a boost ratio between an input voltage and an output voltage smoothly. Another object of the invention is to provide a simple power converter for driving a five-phase switched reluctance motor. Two pairs of one reactor and one DC power resource are connected in series with a series switch. Moreover the two pairs are connected in parallel via two parallel switches. Each of the two pairs is short-circuited via the series switch by each of the parallel switches. The five-phase power converter applying five phase voltages to five phase windings of a switched reluctance motor has at least six transistors and six freewheeling diodes. two phase windings of five phase windings having a star connection configuration is turned on simultaneously and turned off simultaneously. One of the two phase windings is connected to a high potential line and the other one of the two phase windings is connected to a low potential line, when two transistors are turned on simultaneously.
