Title:
カスケード接続型2レベルコンバータにおいて行なわれる方法、制御装置、及びコンピュータプログラム製品
Document Type and Number:
Japanese Patent JP2012517786
Kind Code:
A
Abstract:
A method for providing a switching order signal to a cell of a cascaded two-level converter is provided. The cell includes a capacitor parallel-connected with two series-connected semiconductor devices. The cascaded two-level converter includes two or more of the cells cascade connected and arranged in a phase, divided into two phase arms, between a first pole and a second pole of a direct voltage side. The method includes measuring voltages of the capacitor of the cell; calculating a compensated voltage reference based on a voltage reference and the measured voltages of the capacitors, wherein the voltage reference corresponds to a desired ac current to be output on an ac-side; using the compensated voltage reference to calculate a switching order signal, and providing the switching order signal to the cells.
