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

Calculate the resonant expeatency:

f 1; FLT; 0 = FLT: 0 = 10 = 10; FLT: 2: 33; -6 MIS3; FL3: 3; 33O = 10 = 10 = 10; 2 = 2 FLT; 23222222221f; -322222222222222222121222212121222222212111f; -1212122212222222222221212121212122221111f; -111111f; -1121f; -121112121111111111111111111111111111f; -3; -1t1tf; -1tf; -1tf; -1tf; -1t1t1t1t1t1t@@
