Cut-off frequency calculation method and the output LC filter setting
No.A1567-18/30
RL

CL
L
The cut off frequency fc of the output LC filter is calculated by the following formula.
fc =
1
2
π√2LCL
Also, by setting the cut off frequency fc, the value of CL and L is calculated by using the following formula.
CL =
1
2
√2 × π RLfc
L =
√2 × RL
4
π fc
In general, the value from 20% to 30% of CL is set to C.
In case of fc = 30kHz
RL [Ω]

CL [μF]

Above formula is common calculation method and is a measure of constant setting.
In fact, it is necessary to set with each set that considers the speaker characteristics.
In addition, please set the fixed number to become Q
≤ 1 in currents in the fc neighborhood increasing if Q value of the LC
filter is big.
