PFC Boost Converter Calculator

Design active power factor correction (PFC) boost stages for AC-DC power supplies.

Input Voltage V_{in_rms} (V)

Output Voltage V_out (V)

Output Power (W)

Switching Frequency (kHz)

Inductor Ripple (%)

Efficiency η (%)

Duty: D = (V_out-V_pk)/V_out

Inductor: L = V_pk×D/(ΔI×f_sw)
