In response to the increasingly stringent CO2 reduction strategies by the International Maritime Organization (IMO), active development of technologies is underway, among which the shaft generator system is emerging as the most realistic energy efficiency improvement technology with rapidly growing demand. Since the shaft generator shares its shaft with the ship's main engine, a shaft generator drive is necessary to stably integrate fluctuating output voltage and frequency into the power system. Controlling the direct current (DC) voltage of the drive is crucial for enhancing the quality of power during system integration. Recently, active rectifier utilizing power semiconductors have been applied for this purpose. In this paper, perform a comparative simulation using Matlab/Sim-ulink to analyze the control and output characteristics of active rectifiers, under conditions identical to those of diode rectifiers. The results demonstrate that active rectifiers can maintain the commanded voltage despite fluctuations in the input voltage and frequency of the shaft generator and keep the voltage ripple rate within 1%, showing superior output characteristics compared to diode rectifiers.
