AIF - PFC Power Factor
Correction Series
RMS ripple current
The maximum permissible rms ripple current for the output capacitor should be greater than the rms ripple current for the
application. The ripple current for the PFC module can be approximated as
I
rms = (PO/Eff)
x 1/
√(V
O x Vrms)
where :
P
O = output power (W)
Eff = efficiency
V
O = output voltage (V)
V
rms = input rms voltage (V)
This gives the ripple current at 125KHz. The maximum ripple current for capacitors is usually specified at 120Hz. To convert
from 125KHz to 120Hz the Irms figure should be divided by 1.3 .
Peak to Peak Output Ripple Voltage
The ac input causes a ripple on the output voltage. The size of the ripple is inversely proportional to the size of the capacitor.
Therefore the maximum allowable ripple voltage should be decided in order to calculate the size of capacitor required. This
may be calculated using the following equation:
C
O = PO / (2πf x Eff x VO
x V
ripple)
where :
C
O = output capacitance (F)
Eff = efficiency
f = input voltage frequency (Hz)
V
O = output voltage (V)
V
ripple = output ripple voltage (V)
Hold-Up Time Requirement
The output capacitor value is different for different hold-up time requirements. The minimum capacitance corresponding to
the required hold-up time of a system comprised of ASTEC DC/DC power modules and an PFC module can be calculated as
follows:
C
O min = (2 x PO x Thold)/[(VO-Vripple)
2
- (V
min)
2
]
where :
C
O min = output capacitance (F)
P
O = output power (W)
T
hold = hold up time (sec)
V
O = output voltage (V)
V
ripple = output ripple voltage (V)
V
min = minimum input voltage for DC/DC module
