| 20090034305 | Power Conversion Device and Power Conversion System - A power conversion device includes input terminals, first output terminals, second output terminals, and an insulation transformer. The insulation transformer includes a primary coil and a secondary coil of equal inductance. The polarity of one end of the primary coil is same as the polarity of the other end of the secondary coil. One of the first output terminals is connected to an input terminal and the one end of the primary coil. The other of the first output terminals is connected to an input terminal and one end of the secondary coil. One of the second output terminals is connected to the other end of the primary coil and the other end of the secondary coil. The other of the second output terminals is connected to an input terminal. | 02-05-2009 |

| 20090256161 | POWER CONVERSION APPARATUS - In the case where a chip is made of wide band gap semiconductor, a power conversion apparatus is obtained in which a component having a low heat resistant temperature is prevented from receiving thermal damage by heat generated at the chip. In a configuration including: a chip portion ( | 10-15-2009 |
| 20110013440 | RECTIFIER CIRCUIT - Switches perform switching at a timing when a first phase voltage and a second phase voltage outputted from a three-phase voltage source have a phase difference of 90°. Then, a three-phase/two-phase conversion inductor outputs a pair of AC currents, and a rectification and a single-phase pulse-width modulation are performed on each of AC currents. Modulated currents obtained as a result of the rectification and the single-phase pulse-width modulation are synthesized, to generate an output current, which is supplied to a circuit in which a capacitor and a load are connected in parallel with each other. | 01-20-2011 |

| 20090090546 | SUBSTRATE FOR AC/AC MULTIPLE-PHASE POWER CONVERTER - A substrate includes a plurality of input ends, a plurality of output ends, first and second direct-current power lines, a first region and a second region. An alternating voltage is applied between any two of the input ends. The first region permits mounting of any one of a plurality of kinds of first surface-mount devices that selectively establishes electrical continuity between one of said plurality of input ends and either said first or said second direct-current power line. The second region permits mounting of a second surface-mount device that selectively establishes electrical continuity between one of said plurality of output ends and said first or said second direct-current power line. | 04-09-2009 |
| 20100226152 | INVERTER - The inverter includes an electrolytic capacitor which receives DC power, a series resonant circuit connected in parallel with the electrolytic capacitor, and a switching device group which converts the DC power into AC power by switching using pulse width modulation. | 09-09-2010 |
