STEVAL-ISV002V1 3000 W photovoltaic converter for grid-connected applications
In recent years, interest in photovoltaic (PV) applications has grown exponentially. Because PV systems require an electronic interface to be connected to the grid or standalone loads, the PV market has become appealing for many power electronics manufacturers.
The STEVAL-ISV002V1demonstration board implements a conversion system for PV applications with the aim of achieving high efficiency and significant reduction in production costs. It consists of a high-frequency isolated input power section which performs the DC-DC conversion, and an inverter section capable of delivering sinusoidal current at 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 unique characteristics of the proposed converter are integration level, decoupled active and reactive power control and flexibility towards the source.
A fully digital control algorithm, including power management for grid-connected operation and MPPT (maximum power point tracking) algorithm, has been implemented on a dedicated control board, equipped with a latest-generation 32-bit (STM32) microcontroller.
