DC-DC Voltage Doubler (simplest Possible Circuit)

About: Music: my profession for over 40 years... Electronics: my beloved hobby always.

Intro: DC-DC Voltage Doubler (simplest Possible Circuit)

This voltage doubler circuit uses a DPDT switch to alternately charge 2 series connected capacitors. The main purpose of this circuit is to illustrate the principle of operation of switched-capacitor voltage multipliers. Other applications are up to you !
