[ P_z = V_z \times I_out = 12 \times 0.05 = 0.6W ] → use 1W Zener. 4. Efficiency Analysis Efficiency ( \eta = \fracP_outP_in ). Input power measured via wattmeter simulation.

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

where ( f ) = line frequency (50/60 Hz), ( C ) = dropper capacitor. [ P_z = V_z \times I_out = 12 \times 0

Assuming full-wave, the RMS input current equals output DC current (approx). Input power measured via wattmeter simulation

[ X_C = \frac12\pi f C ]

Choose standard value ( C = 0.68 \mu F ) (X2 safety capacitor).

Parallel to C to discharge when unplugged: ( R_bleed = 1M\Omega ).
