Development of a new Grid-connected Inverter based on DSP

Texas instrument DSP TMS320LF2407A is used as core to develop a new gird-connected inverter and produce SPWM to drive MOSFET,track output current,switch between gird-connected and independent work etc..The maximum power point tracking,isolated island observation and phrase synchronization are analyzed.This new inverter improves solar energy conversion efficiency by real time solar tracking and a new maximum power point tracking algorithm.
