Abstract

This paper presents development of 200 kW grid connected PV inverter. 200 kW Grid connected PV inverter has the utility frequency transformer for the galvanic isolation between DC and AC, and its output is 3-phase 3-wire 60 Hz, 380 V. P&O algorithm is used for the maximum power point tracking (MPPT) and the active frequency drift scheme for the antiislanding protection. The inverter is controlled by 32 bit DSP. This paper explain the performance and test result of utility interface, anti-islanding, efficiency and THD of 200 kW grid connected PV inverter.
