Abstract :
Weight reduction of the LCL filter is one of the main concerns for high power, grid connected, voltage source converters (VSC) where an LCL filter can weigh hundreds of kilograms. It is a multi-domain optimization issue to find the minimum weight of an LCL filter considering PWM, control, filter design, and magnetic components with given constraints such as harmonic standards, semiconductor power loss, and cooling condition. The comprehensive design procedure and limits of an LCL filter for a 1.2-MVA VSC is provided in this paper.
