This paper presents the design and simulation of a single-phase inverter for Uninterruptible Power Supply (UPS) using the Verilog Hardware Description Language (HDL) co-simulation by interfacing MATLAB/Simulink and ModelSim. The PWM signal was produced by comparing Sine Wave and Triangular Wave digitally generated by Verilog HDL. The analog and digital of the UPS circuit were simulated in MATLAB/SIMULINK and ModelSim Altera software, respectively. The digital controller was simulated using cosimulation tools in MATLAB/SIMULINK. As system developers and researchers work on the same platform, it reduces the required time required in translating the technical specifications into functional specifications. ModelSim works as HDL (Hardware Description Language) simulator. The designed circuit and obtained simulation results are presented in the paper to confirm the performance of digital implementation for this single-phase UPS system. © 2021 IEEE.
