    摘要: A power conversion apparatus includes serially connected arms U and X, serially connected arms V and Y, serially connected arms W and Z, and a capacitor, the pairs of serially connected arms and the capacitor all connected in parallel to one another. The input-side arms U and X and the output-side arms W and Z are subjected to PWM control so that the arms W and Z are controlled to have a voltage that is lower than that of the arms U and X, thereby providing a step down operation. A step up operation also can be provided by an opposite relation in which the arms W and Z are controlled to have a voltage that is higher than that of the arms U and X, thereby to expand the range within which the output voltage is controlled with the effect of reducing distortion.

    摘要: An uninterruptible power supply includes a first converter connected in parallel with an AC power system, a second converter series-connected to the first converter, and an energy accumulation device connected between the first and second converters. A control apparatus controls the first converter and the second converter so that when the voltage of the AC power system is within a first voltage range, the second converter switches at a frequency of the AC power system and the system voltage is output via the second converter. When the system voltage is within a second voltage range, outside the first voltage range, the second converter is used to compensate the voltage of the AC power system to output a reference voltage value, and when the system voltage is outside the second voltage range, the energy accumulation means and the second converter are used to generate and output the reference voltage value.

    摘要: A power-converting apparatus features the ability to achieve initial charging of a smoothing capacitor generating a minimum rush current by obviating the need for additional series connections in a battery, and also obviating the need for an initial charging circuit consisting of a charging resistor and switch in the capacitor. The power-converting apparatus includes a separating device that electrically separates an AC power-supply source from the input devices of the power-converting apparatus, an AC/AC converting circuit that initially rectifies AC current from an AC power-supply source and then causes a capacitor to smooth the rectified AC current, thereby converting the rectified AC current into DC current before again converting the DC current into AC current, a battery; and a DC/DC converting circuit that enables a capacitor to be charged with DC voltage delivered from the battery, and conversely enables the battery to be charged with a DC voltage delivered from the above capacitor bilaterally or unilaterally.

    摘要: An uninterruptible power supply system prevents an output voltage from dropping due to an operation delay of a relay for isolating an alternating-current power source side and avoids an unexpected current flowing between the alternating-current power source side and the uninterruptible power supply system side. When short circuit occurs, a parallel converter connected in parallel to input terminals connected to an alternating-current power source is made to operate so that the output voltage thereof becomes “0” or the input voltage Vin and a series inverter connected in series between an input relay and one of output terminals is made to carry out a compensating operation with a smoothing capacitor taken as a power source so that a value of an applied voltage to the output terminals becomes an output voltage command value Vout*. This makes the output voltage of the parallel converter become “0” or Vin to produce no electric potential difference between the alternating-current power source side and the output side of the parallel converter. Therefore, no current flows between the alternating-current power source side and the parallel converter, and a value of an applied voltage to the output terminals is to be continuously maintained at the output voltage command value Vout* by the series inverter.

    摘要: This invention relates to a composition characterized by containing, as essential components, deacetylated chitin and/or a deacetylated chitin derivative, and glyoxylic acid; a solution-containing gel formed from the composition; a water-insoluble chitosan coating; and a material obtained by treating a base material with the composition. According to the present invention, it is possible to provide a chitosan composition, which in a “one-pack” form, has a pot life. Even when dried at room temperature after coating or impregnation of a base material, the chitosan coating can be water-insolubilized with reduced yellowing.
