摘要： In a projection image display apparatus, a noise removal filter portion 15 is separated from a power source unit body 14. The separated noise removal filter portion 15 is provided in the vicinity of a side wall of a housing on which a power source inlet is provided, and of the power source unit body 14, respectively. Specifically, the power source unit body 14 is provided along a side wall of a front face of the horizontally-long housing of the projection image display apparatus and the noise removal filter portion 15 is provided in a position opposed to the power source unit body 14 in a side wall of the back face. As a result, even when a light source lamp has a higher output, the projection image display apparatus can achieve reduced noise by an improved cooling capability and reduced cost enabled by an efficient Electro Magnetic Compatibility (EMC) measure and the like.

摘要： A duct was configured such that an incident side and an outgoing side of each of liquid crystal panels 34r, 34g, and 34b are formed with discharge ports r1 and r2, g1 and g2, and b1 and b2 to discharge the air from fans 41 to 43 through ducts 411 to 431, and at the same time, a PBS 28 for aligning the polarizing direction of the light from a light source lamp is formed with a discharge port p1 to discharge the air from the fan 43 through the duct 432, and an incident side discharge port b1 and an outgoing side discharge port b2 of the liquid crystal panel 34b corresponding to the blue light are formed with the ducts so as to discharge the air from the fans 43 and 41 which are different from each other. As a result, even when an amount of light per unit area of high luminance is increased, the liquid crystal panels and the polarizing plates and the PBS can be effectively cooled by three sets of the fans.

摘要： Systems and methods for controlling a modular three-phase converter including two or more interleaved, parallel connected Voltage Source Converters (VSCs) utilizing a hybrid Space Vector Pulse Width Modulation (SVM) control scheme are provided. For the hybrid SVM control scheme, six active vectors utilized for SVM define six sectors in a space vector plane. Each sector is divided into two or more regions having corresponding optimal SVM switching sequences. In operation, a revolving reference voltage vector is sampled to provide a reference voltage vector. The SVM controller then identifies one of the regions in one of the sectors that corresponds to an angle and, in some embodiments, a magnitude of the revolving reference voltage vector and applies the corresponding optimal SVM switching sequence to the two or more interleaved, parallel connected VSCs.
