摘要： In a system to which a fluctuating load is connected, compensating for fluctuation in voltage harmonics at the load connecting point and fluctuation in system current harmonics has been difficult for a power converting device connected in parallel with the load. To resolve the problem, a power converting device connected in parallel with a fluctuating load includes: a Fourier series expansion unit which executes Fourier series expansion to load current by use of a reference sine wave in sync with a system and thereby outputs Fourier coefficients; and a fundamental component calculating unit which calculates a positive phase active fundamental component of the load current from the Fourier coefficients. A current instruction of the power converting device is generated by subtracting the fundamental current from the load current. With the current instruction, the fluctuations in system current harmonics and in voltage harmonics at the connecting point can be compensated for.

摘要： A semiconductor power converting apparatus including at least one series arrangement of MOS control semiconductor devices such as Insulator-gate Bipolar Transistors (IGBTs) or metal oxide MOS transistors which are respectively applied with a gate voltage under the control of corresponding a driver. The driver contains a supply line having a higher potential than a gate voltage of an IGBT coupled thereto when the IGBT is in a steady ON state, and is such that is causes an increase of the gate voltage of the IGBT in accordance with the current of the supply line when a potential difference between the power supply line and an emitter of the IGBT is constant and the collector voltage thereof exceeds a predetermined value under an ON state of the IGBT.

摘要： A power conversion apparatus has a circuit configuration in which a collector voltage of an IGBT is divided. It also has a unit which protects the IGBT against overvoltages applied to the collector by outputting a potential of a voltage dividing point to a gate of the IGBT. A case of a resistor on the high-voltage side of the voltage dividing point is fixed to an emitter potential of the IGBT.
