Abstract
This paper analyzes the unbalancing problem of neutral-point voltage with light load in DC-Rail ZVT softswitching inverter. Description of the unbalance reason and the influence to the circuit operating process are detailed through theoretical analyses, and then the schemes of solving this problem are presented. Finally, the scheme feasibility is verified by relative experiments.
