摘要： To suppress a DC component in AC power in a power converter for converting DC power to AC power. DC power is converted to AC power by a converter 2, and the AC power is supplied to output terminals u1 and u2 via an inductor 3. The converter 2 is controlled based on an error Δ(t) between an output current iP(t) outputted from the converter 2 and a target current j(t) outputted from a target current generation means 110 as a target value for the output current iP(t), and a DC component VD in an output terminal voltage v (t) is detected by a voltage detection means 18. A DC component ID is suppressed by correcting a target current j(t) by a DC component suppression means 8. Also, a DC component in the AC power is suppressed to prevent biased magnification of a transformer 4 by calculating a correction amount jh(t) for correcting the target current j(t) from the difference between a first instantaneous value d1 of a load current is(t) flowing to a load 4 at a first time point t1 and a second instantaneous value d2 of the load current is(t) at a second time point t2 that is a half cycle after the first time point to correct the target current j(t).

摘要： A single-phase voltage source AC/DC converter according to the present invention generates a second axis voltage command from difference between a DC voltage detection value at a DC terminal and a DC voltage command value and controls a DC voltage by increasing and decreasing active power with the second axis voltage command. For example, the voltage at the DC terminal is increased by decreasing active power when the DC voltage detection value at the DC terminal is lower than the DC voltage command, while the DC voltage detection value at the DC terminal is decreased by increasing the active power when the DC voltage detection value at the DC terminal is higher than the DC voltage command.

摘要： An automatic synchronous parallelization apparatus capable of suppressing an inrush current by automatically adjusting the magnitude, the frequency, and the phase of the voltage when a single-phase voltage-type DC-to-AC converting device performing an autonomous parallel operation is connected in parallel with an external single-phase AC voltage source. The automatic synchronous parallelization apparatus includes a synchronization detecting circuit, a voltage amplitude command value generating circuit, and a frequency command value generating circuit. The voltage amplitude command value generating circuit generates the 1st-axis voltage command value, and the frequency command value generating circuit generates the 2nd-axis voltage command value, based on a value relating to a frequency difference between an external single-phase AC voltage source and a single-phase voltage-type DC-to-AC converting device and an effective value of a voltage of the external single-phase AC voltage source that are detected by synchronization detecting circuit. By using such command values, an output of the single-phase voltage-type DC-to-AC converting device can be adjusted to as to coincide with a voltage waveform of the external single-phase AC voltage source.

摘要： A method and a single-phase voltage type AC/DC converting device and a three-phase voltage type AC/DC converting device arranged between a load and a distribution network. The converting devices are capable of contributing to stabilize a system frequency and a system voltage. By applying an autonomous parallel operation control technique of an AC/DC converter to a load, which receives power from a distribution network, drooping characteristics (governor-free characteristics) for a frequency of active power and voltage-maintaining characteristics (V-Q characteristics) may be obtained. The governor-free characteristics automatically decrease and increase received power when the system frequency decreases and increases, so that even the load may contribute to stabilize the system frequency. The V-Q characteristics generates/absorbs reactive power so as to maintain a voltage at a receiving end constant regardless of load power to further stabilize the system voltage.
