Single-Phase Inverter Reference Design With Voltage Source and Grid Connected Modes
Description
This reference design implements single-phase inverter (DC-AC) control using the C2000™ F2837xD and F28004x microcontrollers. Design supports two modes of operation for the inverter. First is the voltage source mode using an output LC filter. This control mode is typically used in uninterruptible power supplies (UPS). Second is grid connected mode with an output LCL filter: which is typically used in solar inverters. Firmware for the design is supported under the powerSUITE framework which enables adaptation using the Solution Adapter and enables tuning of the control loop using the Compensation Designer and SFRA. High-efficiency: low THD and intuitive software make this design attractive for engineers working on inverter design for UPS and alternative energy applications such as PV inverters: grid storage and micro grids.
