Calculating the Resonant Frequency
Resonansi ini sering terjadi (f 1st; FLT: 0: 33; res res 1; FLT: 1; 1f 3;;) can be kalkulated using formula:
FL1; FLT: 0 AF3; f 1; FLT: 1: 1 ASA3; REs 1; FLT: 2: 3; ASA3; = 1 / (L × C) 41; FLT: 3 SyL3;
Dimana:
- 1f 1f; 1f; FLT: 0 133; L 1f; FLT: 1 1f 3; = Total inctance in henrys (H)
- S01; WAL1; FLT: 0 ASA3; C ASA1; FLT: 1 ASA3; = Tatachitanpe farads (F)
To perform the kalkulation:
- Measupe or obtain te inductance and capacitanpe values.
- Convert units to henrys and farads if neeariy.
- Insert the values tne te to te formula and communte.

Supposeahn LLC converter has ahn inictance of 10 zH and a cacacapitanpe of 100 nF. Convert units:
10 = 10 × 10 = 10 = 10; 1f 1; FLT: 0 133; Aver3; -6 111; FLT: 1 3; HH
100 nF = 100 × 10 = 10 = 11; FLT: 0 123; 1st = -9 11f; FLT: 1 3; 13; F
