  This paper presents current control method for a grid-connected partial
resonant soft switching inverter. This inverter does not use an electrolytic
capacitor and is capable of boosting and bucking the voltage. Grid-connected
inverters are used to integrate distributed energy sources to the grid. Current
control is vital in meeting the standards and requirements when connecting to
the grid. The closed-loop current regulation for this type of converters is
analyzed and design guidelines are provided. The control is implemented in the
synchronous frame. In addition active damping techniques using capacitor
voltage and inductor voltage feedback is used to mitigate CL filter resonance
at the output. The mentioned control strategies are implemented on a 400W lab
prototype and the results are presented
