Abstract
In order to solve the current harmonic and voltage regulation problems of three-level boost converter operating in discontinuous conduction mode, a circuit parameter optimization method is proposed. The continuous-time-domain mathematical models under four basic modes are established, and the output voltage gains are derived in two conduction modes. Different conduction modes are compared and analyzed from several aspects to improve the system’s performance. In this paper, the critical conduction conditions are derived to optimize circuit parameters, guaranteeing the system to work in continuous conduction mode in the entire duty ratio. Finally, the correctness of theoretical analysis is verified by simulation results.
