摘要： A power converter includes a rectifier section, an inverter section, a capacitance element connected between inverter section input ends, an inductance element forming part of an LC filter with the capacitance element, a voltage detector detecting an inductance element voltage, and a controller controlling the inverter section based on the detected voltage. The LC filter has a resonance frequency set such that ripple current components contained in DC current outputted from the rectifier section passes through, and current components of a frequency equal to a carrier frequency of the inverter section are dampened. The controller controls the inverter section so that a transfer characteristic of input voltage of the inverter section versus the DC voltage from the rectifier section becomes a damping characteristic given by a phase lead element and a second-order lag element connected in series, and a damping coefficient of the transfer characteristic is set larger than 1.

摘要： A cycle is divided into a first period and a second period. The first period is longer than the second period. Two sections in which a unit voltage vector is adopted in the first period are adopted as a first section and a second section. A first measured value of a link voltage is measured at a midpoint of the first section and a second measured value of the link voltage is measured at a midpoint of the second section. Then, a representative value of the link voltage in a cycle including the first period is obtained by interpolation of the first measured value and the second measured value. A maximum value of the link voltage is obtained by dividing the representative value by cos θ.

This AC component has a frequency which is six times a fundamental frequency of an AC voltage outputted by the inverter.

摘要： A power converting apparatus generates a carrier having a waveform in which an absolute value of a slope is constant with respect to time, based on a value for internally dividing amplitude of the waveform into first and second values. Commutation of a converter is performed when the carrier takes a reference. Adoption is allowed of a zero voltage vector as a switching mode of an inverter in a period in which the carrier takes a first command value to a second command value. A value for internally dividing a value from the reference to a maximum value of the carrier at a ratio between a third value and a fourth value is the first command value. A value for internally dividing a value from a minimum value of the carrier to the reference at a ratio between the third value and the fourth value is the second command value.

摘要： In a direct converting apparatus including a converter and a plurality of inverters, substantial carrier frequencies of the plurality of inverters are made different from each other while performing an operation in synchronization with the converter. An original carrier has a carrier frequency twice as high as a carrier frequency of a first carrier used for controlling one of the inverters. A waveform of the original carrier is magnified twice with a value serving as the center thereof, so that a second carrier used for controlling the other of the inverters is obtained.

摘要： A switch device is brought into conduction in a case where a carrier takes a value zero to drt, a switch device is brought into conduction in a case where the carrier takes a value the drt to one, and one cycle of the carrier is divided into a period in which the carrier has a command value or more and a period in which the carrier has the command value or less. The periods are calculated by dst·T and drt·T, respectively. The same one as the carrier of a converter is employed in a carrier of an inverter, and based on the value drt set as a reference value, a command value of the inverter is provided in each of a side with a value larger than the reference value and a side with a value smaller than the reference value. The period in which the carrier takes the value or more is divided at a ratio among d0, d4 and d6, and the period in which the carrier takes the value drt or less is divided at the ratio among d0, d4 and d6.
