摘要：
A switching circuit with switches between a charging path and a low-impedance active path. The charging path comprises a zener diode substantially in parallel with a charging capacitor. Current flows through the charging path when the circuit is powered on and a power supply charges the charging capacitor while current flows through the charging path. The low-impedance bypass path comprises a switch that remains closed until a voltage across the charging capacitor exceeds a threshold voltage. The switch opens when the charging capacitor exceeds the threshold voltage.
