Summary: A novel single-phase single-stage transformerless inverter is proposed in this article for grid-tied and standalone applications, featuring low leakage current and the ability to perform both buck and boost functions. This inverter can achieve high power density and conversion efficiency, as only one switch operates at a high frequency. Additionally, there is no need for inserting high-frequency dead-time between the switches, leading to improved performance.

Summary: The article proposes a composite-bisection predictive control (CB-PC) method to simultaneously achieve DC-link voltage stabilization and load voltage control in an electrified shipboard power system. It stabilizes DC-link voltage oscillation using an improved general method based on instantaneous power theory and enhances transient response with deadbeat control. Load voltage control is achieved indirectly through tracking an offline-derived inductor-current vector, and a modified bisection algorithm with a tunable iteration number is presented to improve steady-state control performance. Simulation and experiments confirm the effectiveness and robustness of the approach against parametric variations.
