Assuming full-wave, the RMS input current equals output DC current (approx).

This paper investigates the engineering trade-offs: low cost vs. safety, efficiency vs. ripple, and compactness vs. heat dissipation. The circuit relies on the capacitive reactance ( X_C ) to limit current without dissipating significant heat (unlike a resistor). For a sinusoidal AC mains voltage ( V_in(t) = V_p \sin(\omega t) ): asaan converter

: At plug-in, if AC peak coincides with capacitor discharge, ( I_peak ) can exceed 50A, damaging rectifier diodes unless a series resistor (e.g., 10Ω) is added. Assuming full-wave, the RMS input current equals output

: If dropper capacitor fails shorted, full mains voltage appears at output, destroying load and creating fire risk. efficiency vs. ripple
