12. Power Factor Control Circuit
Power factor is controlled by almost 100%. (Effective use of power)
With IC in ACT module, control is performed so that input current waveform will be similar to waveform of input
voltage.

V (input voltage)

(Even if voltage is applied. current does not flow
*Assuming the same current capacity (20A), power can be used about 10% effective, comparing with curent use
(power factor of 90%), and maximum capacity is thereby improved.
