DC DC Power Converters electronics projects

Using this circuit diagram, can be build a simple voltage stabilizer using discrete electronic components.

Using circuit diagram below can be built a voltage converter, able to convert a 70-260V AC to a 180-350V DC voltage.

Using this circuit diagram can be made a very simple voltage converter, which produces an output voltage of about 5V. Voltage converter is built using the MC34161 chip manufactured by Motorola, and allows an input voltage between 9.5V and 24V. Because this converter voltage is a switching type, dissipate very low heat . Maximum steady state current is 250 mA, although it can cope with peaks up to 750 mA.
