摘要： A method and a device to discharge cell capacitors in a cell based voltage source converter. Each cell has switching elements in half bridge or full bridge configuration and a capacitor in parallel to the half or full bridge. Each cell has two terminals, whereof at least one is between two switching elements. The converter has AC and DC terminals, with the possibility to connect each of the terminals to ground, via a further switching element. A resistor is implemented into at least one of the ground connections. To discharge to capacitors, the switching elements in the respective cells are configured such, that the capacitor is in parallel connection to the terminals. The capacitors are thus discharged via the resistor to ground.

摘要： A device for converting a DC voltage into an AC voltage and vice versa comprises a control system to control the voltage conversion and at least one phase leg (1) with a first (Uvp1) voltage source connected in series between a first DC terminal (4) and a first AC terminal (6) and with a second (Uvn1) voltage source connected in series between the first AC terminal (6) and a second DC terminal (5). Each of the voltage sources comprises at least a first and a second submodule (15) in series-connection, where each submodule (15) comprises at least two power electronic switches (16) connected in parallel with at least one capacitor (17). The control system comprises a central control unit (19) and at least two subunits (20), where the central control unit (19) transmits to each subunit (20) a reference AC voltage (ua_ref) and a switching carrier signal (s_sw) and where each subunit (20) controls the switching of the power electronic switches (16) of one of the submodules (15) according to a PWM pattern so that each time the switching carrier signal (s_sw) crosses the reference AC voltage (ua_ref) either the voltage across the capacitor (17) or a zero voltage are applied to output terminals (26, 27) of the corresponding submodule (15).
