– The concept of Direct Current distribution system for hybrid-powered trimaran ship is proposed by rectifying the voltage of diesel generator using a three-phase rectifier. Then, power is transmitted using DC. In order to control the electric power, DC-DC Converter is used to step up and step down the voltage. Before entering each load, the Direct Current will be converted into Alternating Current by the inverter. This research focuses on the implementation of a buck and boost converter on the direct current distribution system for hybrid-powered trimaran ship. The initial design of the buck and boost converter has been to determine the parameters of input voltage (Vs), output voltage (Vo), switching frequency (fs), output power (P), the percentage of voltage transfer, the ripple factor of input current and the ripple factor of output current. These initial parameters design aim to determine the value of the load, the inductor, and the capacitor. The buck-boost converter has been successfully simulated and implemented in order to stabilize, step-up and step-down the voltage. The DC voltage that comes out of the buck-boost converter tends to be more stable and it has a smaller voltage ripple than before entering the converter. The energy flow in the buck-boost converter occurs in the voltage transfer capacitor, so the voltage value produced is more stable. The buck-boost converter has an input side inductor which functions as a filter for the input voltage wave ripple.
