Abstract This paper analyzes input voltage sharing control theory of input-series output-parallel (ISOP) inverter. On the basis of the control theory, a novel distributed voltage sharing control strategy is proposed to solve input voltage sharing problem. Compared with the centralized control strategy, the distributed control strategy makes each module with independent control system and working independently. It is convenience to make up ISOP inverter by connecting modules with communication lines. The distributed voltage sharing control strategy improves modularization and reliability. This paper also analyzes working principle of the distributed control strategy, and gives some experimental results to valid it.
