Voltage Doubler from 6VDC to 12VDC

Voltage Doubler from 6VDC to 12VDC
This is the circuit diagram of voltage doubler, or it can be called DC to DC converter circuit, from 6 Volt DC become 12V DC. This dc voltage doubler circuit will need about 2A from the 6V input supply to produce the full 800mA at 12V for the power output. (more…)

24v to 12v converter

24v to 12v converter
As shown, the 24v to 12v converter circuit is nothing more than an integrated adjustable voltage regulator that acts on a group of power transistors in parallel. These transistors can be said to perform heavy duty while the regulator responsible for controlling them. (more…)

DC to DC Converter 5V to 30V

DC to DC Converter 5V to 30V
This DC to DC Converter 5V to 30V schematic will convert +5 volt input voltage to +30V voltage. Direct current is converted into an alternating generator, which built on having the characteristic hysteresis inverter with Schmitt trigger and a resonant circuit. At the rectifier output voltage is formed with a doubling of high voltage 50 V. (more…)

Stable Power Supply for High Voltage -100V to -1000V

Stable Power Supply for High Voltage -100V to -1000V
Stable power supply for high voltage power supply for the core of a high voltage of the PWM - Controller TL494, loaded with over 4050 followers on a pair of powerful field-effect transistors, switching the primary winding of step-up transformer (4 + 4 turns - the primary winding, 200 turns - the secondary winding). With the secondary winding through a rectifier with voltage doubling and smoothing filter RC LC voltage reaches the voltage divider, and the regulator output voltage.

DC to DC Converter 12 Volt to 21 Volt

DC to DC Converter 12 Volt to 21 Volt
Below is a schematic diagram of a DC to DC Converter 12 Volt to 21 Volt by using IC TDA2003. This 12 V to 21 V DC to DC Converter can perform nicely at 500mA maximum current. In case the current exceeds 500 milli-amperes, the voltage will drop below 21 Volt. (more…)
