This reference design is a digitally-controlled, grid-tied, single-phase, full-bridge DC/AC inverter stage for use in central or string solar inverters. It is a companion to TIDM-SOLAR-DCDC, a front-end DC/DC converter with maximum power-point tracking (MPPT). Together, TIDM-SOLAR-DCDC and TIDM-SOLAR-ONEPHINV comprise a solar inverter for central or string topologies. C2000™ F28M35H52C microcontroller (MCU) is the digital controller for the full-bridge DC/AC inverter stage, efficiently operating the inverter stage while implementing Ethernet-based remote control and monitoring of the inverter. The inverter output is grid tied with anti-islanding protection. This design achieves total harmonic distortion (THD) of less than 5 percent and full-load efficiency greater than 96 percent, providing more energy extraction from a solar installation, reducing detrimental heat dissipation in the inverter and increasing inverter longevity.
