Conclusion
According to the findings of this study, when the one-converter method is adopted, the power factor
states the value 0.748 which is not tally with rules from the Suruhanjaya Tenaga’s procedure.
However, if the power factor value is less than 0.85 (PFC = 132kV), a surcharge will be imposed on
the consumers. By using the method 2 and 3, the PFC value is more than 0.85 which is better than the
previous method. On the other hands, method 1 show the sag and swell voltage (using passive
components), method 2 is better but method 3 because used more inductor the swell voltage was
happen. So, it mean the performance of sag and swell voltage is depends on the voltage input, and
power converter (PFC).
In conclusion, the performance of Power Correction Methods (PFC) is depends on the voltage
input and loads. It implies that all home appliance ranging from socket outlet, input supply (DC
supply) and the loads must be considered. The consideration must be based on the supply
performance. This is due to the fact that the value of power factor correction is proportional with the
voltage input. The performance sag and swell voltage between the power converter topologıes is also
provided in this paper.
