[ X_C = \fracV_in,RMS - V_zI_out = \frac230 - 120.05 \approx 4360 \Omega ]
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
Assuming full-wave, the RMS input current equals output DC current (approx). [ X_C = \fracV_in,RMS - V_zI_out = \frac230 - 120
: If dropper capacitor fails shorted, full mains voltage appears at output, destroying load and creating fire risk. heat dissipation
where ( f ) = line frequency (50/60 Hz), ( C ) = dropper capacitor.
: 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.
