The paper describes the features of a novel watercooled 690 V high power IGBT inverter design using polypropylene film capacitors in the dc link instead of electrolytic capacitors. The first application is a Power Conditioning System (PCS) with an output of ±9600 kvar to control the reactive power of a 90 MW windfarm in New Zealand steplessly and to feed capacitive current instantaneously into a voltage dip disturbed power supply. Due to its 4-quadrant ability, the PCS is equally well suited for dynamic control of battery energy storage systems.
