100 watt Compact Ferrite Inverter Circuit
A very small and compact ferrite based 100 watt inverter circuit can be built using around the IC 4047 which has an internal oscilator.
The proposed inverter circuit utilizes a small ferrite transformer for acquring the required 220V mains AC.
This 100 watt compact ferrite inverter is just like other like inverter circuits but is compaxct by neture since theres no heavy or bulky transformer used in this design.
The block diagram for the same may be understood as folows:
A 4047 IC is used for geting the bsic oscillations required for any inverter design.
Referring to the given circuit, two 4047 stages could be seen for the required actions.
The upper 4047 IC is riged as a high frequency oscillator, the given should be adjusted to acquire around 60kHz frequency over the connected mosfets.
Once initiated the mosfets conduct in a push-pull manner inducing the entire battery volatge and current across the primary winding of the associated ferrite E core transformer TR1.
As per th winding configuration, the transformer generaters an equivalent amount of voltage, thats around 220 + 220V across the secondary center tap winding or the output winding.
The lower 4047 IC stage is configured as a 50 Hz oscillator.
Here its pin13 is used as the output for driving a P/N pair of mosfets. These mosfets again conduct in a push pull manner, however since a p/n pair is used, unlike the upper stage here it conducts to produce both the cycles of AC output.
This stage is integrated with the points A and B of the upper 220+220V points, which is appropriately push and pulled alternately by the p/n pair to produce a 220V AC across the shown points at exactly 50 Hz.
The design is a simple 220V square wave type, which could be sutiably modified for getting a sine wave output.
The coil or the main transformer maybe wound on suitable EE type core which may accomodate the following winding data comfortably:
Primary = 6-0-6 number of turns using 1mm diameter super enameled coper wire.
Secondary = 350-0-350 turns using 0.3mm super enameled copper wire

hi, may i know if in one complete circuit, it is composed of two oscillation circuit? in short 2 cd4047 utilize?

Is this circuit tested.
ReplyDeleteé Muito Difícil Conseguir Energia AC Com Transformador de Ferrite.
ReplyDeleteWhat should be the ideal frequency.? And what about voltage stabilization.
