Modelling of the modified-LLCL-filter-based single-phase grid-tied Aalborg inverter

Owing to less conduction and switching power losses, the recently proposed Aalborg inverter has high efficiency within a wide range of input DC voltage for single-phase DC/AC power conversion. In theory, the conduction power losses can be further decreased, if an LLCL-filter is adopted instead of an LCL-filter for a voltage source inverter, mainly due to the reduced inductance. The Aalborg inverte...
