Hi. Today I'll show you a simple yet efficient project for creating high voltage DC for DIY experiments. It's a DC DC Switch Mode Power Supply, or simply a Voltage Booster. The circuit is powered by the UC3843 PWM driver IC. You can boost 12V DC up to 360V DC, and the output is continually adjustable from about 20V-360V. The power capacity is 100-150Watts.
