LLC Resonant Converter Calculator

Professional electronics engineering calculator with interactive results.

Input Voltage V_in (V)

Output Voltage V_out (V)

Output Power (W)

Resonant Frequency f_r (kHz)

L_m/L_r Ratio (k)

Quality Factor Q

Turns Ratio: n = V_in / (2×V_out)

AC Load: R_ac = 8n²V_out² / (π²P_out)

Resonant Capacitor: C_r = 1/(2π×Q×f_r×R_ac)

Resonant Inductor: L_r = 1/((2πf_r)²C_r)
