Flyback Converter Calculator

Professional electronics engineering calculator with interactive results.

Input Voltage V_in (V)

Output Voltage V_out (V)

Output Power (W)

Switching Frequency (kHz)

Max Duty Cycle (%)

Efficiency η (%)

Turns Ratio: n = V_out/V_in × D_max/(1-D_max)

Primary Inductance: L_p = (V_in×D_max)² / (2×P_out×f_sw/η)

Peak Current: I_pk = 2P_out/(η×V_in×D_max)
