Bridge Rectifier vs Voltage Doubler Circuit - Switchable Configuration Explained #3671072 (License: Personal Use)

This schematic illustrates a dual-mode AC-to-DC conversion circuit centered on a diode bridge (Br1), two electrolytic capacitors (C1 and C2), and a control switch (S1). When S1 is open, the circuit functions as a conventional full-wave bridge rectifier; when closed, it forms a Greinacher-style voltage doubler, effectively doubling the peak output voltage. The configuration allows flexible power supply design without changing hardware.

Used in electronics tutorials, power supply design guides, and embedded system documentation to demonstrate reconfigurable rectification techniques. Matches user intent for understanding switchable power topologies, DIY PSU projects, or academic study of diode-based voltage multiplication.
