“…In order to find the values for the outer voltage loop controller, Douangsyla et al (2004) is analyzed to obtain where ξ is the damping ratio, ω n is the undamped natural frequency, u d is the peak of the supply phase voltage, and C is the DC‐link capacitance as described before. The values of ξ and ω n are chosen according to the desired maximum overshoot and settling time.…”

In this paper, an enhanced control scheme for a pulse‐width‐modulated (PWM) voltage source converter (VSC) is proposed for a DC zonal shipboard power system (SPS). First, the main design parameters of VSC such as switching frequency and DC‐link capacitance are investigated and optimized for the SPS application. Then, the nonideal operating conditions such as sudden load change, sudden supply voltage change, and unbalanced supply voltage are considered. To address these issues, the VSC control strategy has been enhanced by (i) adopting a different PWM strategy that changes the carrier frequency under nonideal operating conditions, (ii) adding a negative‐sequence controller, and (iii) implementing an instantaneous phase locked loop (PLL). The results show that the proposed controller shows indeed a satisfactory performance for this specific application and it can also operate at unity displacement power factor under nonideal conditions.

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.
