Abstract:

This study describes a DC to DC voltage multiplier using the 555 Integrated Circuit (IC) timer in an astable state. The major motivation of the design is to be able to produce an inexpensive and light form of generating high DC voltage to power devises that would normal need a really large and heavy battery to be operated. The study also briefly touch on the negative aspects of large DC voltage, heat dissipation and general battery life. With the help of the astable state of the multivibrator, a circuit which uses the same concept found under AC voltage multiplying of using a connection of diode and capacitors to charge the capacitors using the AC nature of rising and lowering voltage levels in a sinusoidal wave, a pulse similar to this will be generated and the same properties and relationship of diodes and capacitors taken advantage of. The study also offers calculations governing the astable 555 timer and practical diagrams on this application. Finally, the study ends with a successful and practical design schematic for a DC to DC voltage multiplier that rises the output DC voltage to about four times the original input.
