2. Boost converter is used as a power factor correction device which increases the value of
power factor. When the value of inductor (in boost converter circuit) changes, this will affect
the power factor and total harmonic distortion values.
Stage 4:
1. Filter circuit in this stage used to reduce the ripple of the waveform and the content of the
harmonics.
2. Non-linear load will also create the harmonics contents in the output value depending on the
impedance.
Results and Discussion
In this section, the results of each method explained above are presented. They are presented
according to sequences in part 2. Besides, there are also simple explanations for each result.

Table I and Figure 5 refer to the summary of Power Factor correction method by using rectifier
passive components converter (Method 1). Based on the table and figure above, when the supply
value is adjusted while the load value remains, the value of PFC is significantly higher and perfect.
A decrease in the supply value will have an effect on the waveform, which the ripple of
waveform becomes higher when the value of voltage is small.
