Digital Controller Implementation of Grid-Tied Zeta Inverter Using 16-bits Microcontroller

A digital control scheme has been presented for grid-tied zeta inverter for single-phase energy storage systems. Over the current key-technique using the flyback inverters, the proposed inverter provides reliable and safe operation mode. It also improves the manufacturing cost of the system by reducing the circuit components. It facilitates the commercial use of the inverter with the proposed control scheme Experimental results have been given to evaluate the performance of the inverter adopting the digital control.
