Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. . This reference design implements single-phase inverter (DC/AC) control using a C2000TM microcontroller (MCU). Design supports two modes of operation for the inverter. This control mode is typically used in uninterruptible. . Challenge: How to reduce Ringing to guarantee increased lifetime of MOSFETs? Si MOSFET have a resistive feature which helps to reduce conduction loss at light load conditions compared with IGBT, but the high reverse recovery of the body diode will increase voltage and current overshoot.
