**How Discrete Voltage Regulator With Current Limiter Works**- voltage regulator circuits and tutorials 5 volt power supply circuit 12 volt alarm power supply 12 volt dc power supply 12 volt to 9 volt dc converter 5 volt power supply 9 volt stabilized power supply adjustable power supply car battery charger car converter for 12 volt to 9v dual regulated power supply dual 12v power supply power supplies there are a number of ways to obtain the low voltages required to run small projects from the wall power outlet the simplest way is to buy a factory built molded supply which is designed to plug directly into the wall outlet presented here is a laboratory power supply with 0 30v voltage and 0 3a current regulation the schematic is pretty straightforward it uses standard dual op s such as tl082 tl062 tl072 ne5532 rc4558 and mc34072 back to smps repair faq table of contents service information advanced troubleshooting if the solutions to your problems have.

not been covered in this document you still have some options other than replacement a simple positive linear regulator there are two basic 723 configurations one for use when the desired output voltage is less than that of the 723 s internal voltage reference vref in the datasheet equal to 7 15v and the other for when it is greater back to sam s schematic collection table of contents adjustable high voltage power supply this circuit uses a pair of 555 timers to provide variable frequency variable pulse width drive to an inverter using a flyback transformer salvaged from a black and white or color tv or puter monitor ltspice 174 is a powerful fast and free simulation software schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits another very important feature of the circuit is the possibility to preset the maximum output current.

which can be drawn from the p s u effectively converting it from a constant voltage source to a constant current in this tutorial you ll learn all about volts watts s ohms current power resistance and kilowatt hours kwh the equations are really quite simple and you ll find some ex les on how to apply them to home appliances power supply to be used as an ex le in this tutorial the power supply below is the one that we ll use as a basis for this tutorial it was designed to be used with audio power lifiers but can be used for virtually anything that needs dc voltage greater than what s
