The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
This paper aims to analyze and optimize output low-pass filters, specifically for current-source, single-phase grid-connected photovoltaic inverters, where the topology chosen is a second-order CL filter, studying different damping resistor placements and investigating the trade-offs involved in developing a comprehensive design methodology.
Serpa, L.A.; Ponnaluri, S.; Barbosa, P.M.; Kolar, J.W. A modified direct power control strategy allowing the connection of three-phase inverters to the grid through LCL filters.
LCL filters are applied to reduce the total harmonic distortion of grid-injected current by inverters. The stability margins of the LCL-filtered grid-connected inverter will be affected by the resonance frequency of LCL filters. This paper design optimal active damping of capacitor current feedback and optimal proportional resonant controller.
