Abstract
Recently, power converters installed on the specialized vessels such as LNG Carrier and Icebreaker and offshore plants mainly use diode rectifier. However, such devices cause distortion of supply voltage waveform by involving much harmonics to input current of non linearity load in rectifying operation. Distortion of supply voltage waveform can be problems such as false operation of generator, transformer and load device and deterioration of power quality. This thesis is focusing with a view to producing accurate sinusoidal AC waveform with certain load through improvement of distortion of current waveform causing under operation of rectifier by using accurate circuit of DC shaping. The result of computer simulation proved that harmonics involved in current and voltage waveform of power system can be reduced.
