The circuit is based on applICation of National SEMIconductor. First is constituted by three voltage regulators LM338 [IC1-2-3] connected `'in parallel' '. The each one regulator has the possibility ...
In a lot of cases we needed a 220VAC voltage, in sPACes where it does not exist, in order to we supply with power, various small appliances. In the Fig.1, exist a voltage converter circuit from 12VDC...
Many times we needed a variety of voltages, from a battery 12V. With the circuit, we CAN take voltages smaller or bigger, positive or negative, from a battery 12V. The idea is based in oscillator rou...
Many times we needed a stabilized, together regulated power supply and high relatively output voltage. These specifICations him it cover our circuit. It 's a circuit that CAN give in his exit + 40V u...
