This application note describes the development and evaluation of a conversion system for PV applications with the target of achieving a significant reduction in production costs and high efficiency. It consists of a high frequency isolated input power section performing DC-DC conversion and an inverter section capable of delivering sinusoidal current of 50 Hz to the grid. The system operates with input voltages in the range of 200 V to 400 V and is tied to the grid at 230 Vrms, 50 Hz, through an LCL filter. Other peculiar characteristics of the proposed converter are the integration level, decoupled active and reactive power control and flexibility towards the source.
