ABSTRACT:
A voltage source converter with a line-side diode rectifier, a load-side inverter with an electronic circuit, a power supply for the electronic circuit, and a slim DC link with a DC link capacitor is described. The slim DC link connects a DC output side of the line-side diode rectifier with a DC input side of the load-side inverter. A buffer capacitor is connected across the power supply, and a decoupling diode and a current limiting circuit are electrically connected in series with the buffer capacitor. The serially connected buffer capacitor, decoupling diode and current limiting circuit are connected in parallel with the DC link capacitor. This arrangement results in a voltage source converter that has an improved service reliability even in unstable power grids, without adding circuit complexity to the line input.
