SEPIC Converter Calculator

Professional electronics engineering calculator with interactive results.

Input Voltage V_in (V)

Output Voltage V_out (V)

Output Current (A)

Switching Frequency (kHz)

Inductor Ripple (%)

Output Ripple (%)

Duty Cycle: D = V_out/(V_in+V_out)

Inductor: L = V_in×D/(ΔI_L×f_sw)

Coupling Cap: C1 = I_out×D/(f_sw×ΔV_C1)
