Low-Cost 1.5 to 9 Volts Inverter

This electronic circuit project is very interesting  and low-cost electronic project,  some electronic circuits we need a 9 volts power supply, but we need to use a battery if that device is mobile. In many cases we don’t have a 9 volts battery or we don’t have enough space to put a 9 volts battery inside the device, so this case we can use a this inverter circuit that will convert 1.5v to 9v to take the place of those expensive 9v batteries.

1.5 to 9 Volts  Inverter  Circuit Diagram:


The input voltage for this inverter can be from 1.5 volts, up to 4.5 volts.  When no current is being drawn from the output the current is less than 10mA.

This inverter circuit is very simple requiring few components, but it can be used only for projects that require low current.  The L1 coil must have 60 turns on a 10 mm ferrite slug 15 mm long, using a 0.25 mm diameter enameled wire.
