Abstract :
In this paper, mathematical modeling and control of a PWM VSC converter is developed for a DC zonal shipboard power system (SPS) application. After selecting suitable controller parameters, a new PWM strategy is utilized by changing the carrier frequency under non ideal operating conditions. Moreover, the effect of different design parameters such as triangular wave PWM carrier frequency and DC link capacitance are observed and using the simulation results, the DC link capacitance size and PWM carrier wave frequencies are optimized for the SPS application. Non ideal operating conditions such as sudden load change, sudden supply voltage change and unbalanced supply voltage are simulated to verify the VSC performance utilizing this new PWM strategy. From the results, it is observed that the VSC can indeed show a satisfactory performance for this specific application and it can also operate under unity power factor under these non ideal conditions.
