Analisa Perancangan Filter LCL Pada Penyearah PWM Satu Fasa Full Bridge
Abstract: Electronics devices
need a direct current power supply although now only one alternating current
power supply is available. Therefore, ac-dc converters which can convert an
alternating current power supply to a direct current power supply will be
needed. However, the use of this ac-dc converters will cause distortion in the
form of current waves which are called harmonics. This harmonics can fault the
work of the other electric devices which are attached to the same power source.
Therefore, it is recommended that the harmonics generated by rectifiers should
be under IEC 61000-3-2 standard. In this research will the reduction of
harmonics by using LCL filter. At load of 2 kW, R of 5 , L of
0,05 H at PWM rectifiers single phase full bridge with RL load produce
the third harmonics current of 2.57 amperes, the installed LCL filter produces
the third harmonics current of 1.26 amperes. According to IEC-61000-3-2
standard, the allowed third harmonics current is 2.3 amperes.
