摘要： PROBLEM TO BE SOLVED: To obtain a power converter which can prevent a switching element from thermal destruction even when a fluctuation such as a momentary voltage drop or voltage imbalance occurs in a connected grid and consequently a momentary AC current being output to the grid changes greatly, causing the switching frequency to increase.SOLUTION: In a hysteresis current control type power converter, each switching element of an upper and a lower arm are switched between on and off to change the polarity of an output voltage so that a deviation between an AC current directive which is a target current to be output to the grid and the detected momentary value of an output AC current fits within the width of upper and lower limit thresholds in reciprocal form, in which way the output AC current to the grid is controlled. The power converter includes means which, when the element temperatures of the switching elements and the working limit temperature are compared and the element temperatures are found to exceed the working limit temperature, stops the on/off control of the respective switching elements of the upper and lower arms.

摘要： PROBLEM TO BE SOLVED: To provide a power converter capable of reducing electromagnetic wave noises by suppressing zero-phase noises by zero-phase canceling control and of efficiently suppressing the occurrence of current distortion in a low frequency range. SOLUTION: The power converter has a control unit 50 for controlling the output voltage of each phase by the total generated voltages obtained by combining the voltage of each phase of a three-phase three level inverter 26 with a plurality of single phase inverters 2, 3, 8, 9, 14, 15. The control unit 50 performs coordinate transformation from a three-phase AC voltage command into a two-phase AC voltage command vector, and selects three spatial voltage vectors having two-phase AC wherein the total three-phase voltage in the vicinity of the two-phase AC voltage command vector becomes zero. Then, a two-phase AC voltage command vector is averaged in time, and is displayed corresponding to the distance from these three spatial voltage vectors to output voltage so as to make a current waveform shaped to a sine wave, while the zero-phase voltage is made to zero.
