AB  - This study presents the design of 3 kW grid-connected PV inverter using boost converter to increase
PV voltage instead of a transformer. Specifically, the key control methods for boost converter and full bridge
inverter are presented. In addition, the PLL technology by using all pass filter is presented. In order to verify
the feasibility of the presented 3 kW PV inverter design, experimental results were presented such as Maximum
Power Point Tracking (MPPT) function and power factor control. According to the experimental results, the
designed PV inverter shows high performances such as 95% MPPT efficiency and 0.99 power factor. The
presented design methodology could be extended to higher power PV application.
