Inverter circuit Use IC CD4047 | 150wattS inverter

Hi Engineers. Inverters are a need in zones with a heap shed or powercuts. Additionally essential in workplaces, shops, and so forth150wattS inverter. With the goal that the essential work ought not be intruded. Today I will examine a 150  Use CD4047 ICwatts inverter circuit utilizing CD4047 IC. This is a steady square wave inverter circuit for ordinary use for table fans, CFLs, Tube lights, TV (LCDs or LEDs as it were). So how about we go further with comprehension and making our 150 watts inverter circuit utilizing CD4047 IC. 

Square chart/Basic plan of an inverter

Above is a square chart indicating the fundamental idea of the working of an inverter. For comprehension, crafted by every component or segment of an inverter, snap to peruse this article. What's more, know the essential working of an inverter and sorts of inverters.

Materials and segments

IC CD4047B

VR1 250K pot - 1pcs

C1 0.02uf or 0.01uf – 1pcs

R2&R3 100R(100 Ohm) 1 watt – 1pcs

Q1 and Q2 IRF540N MOSFETs – 2pcs

Transformer 12-0-12 10A – 15A Transformer( for voltage step-up)- 1 pcs

12V 20 Ah Lead Acid battery | 10 ah for 100 watts

16 pin DIP connector

Misc ( Digital multimeter, patching iron, PCB)


The fundamental parts of this circuit configuration are IC CD4047, IRF540N Mosfets and 12-0-12 15A transformer for voltage step-up( for the most part rang venture Use CD4047 IC transformer as utilized turned around).

CD4047 IC: This is a 16 pin multivibrator IC planned by TEXAS Instruments that have a low force utilization. This IC can work in astable or multivibrator mode in free-running or gateable topologies. Here, it can create a half obligation cycle that is utilized for the inverter circuit.

CD4047 have various applications like recurrence generators, Timer circuits, inverters ( changed sinewave just as squarewave).

The circuits here use CD4047 IC as an astable multivibrator ( free-running oscillator). There is a capacitor between pin 1 and 3. A variable resistor of 250k is associated with the pin2 (Rxx) to set the recurrence of the IC.150wattS inverter

Yields are from pin 10 and pin 11. Pins 10 and 11 yields are setting off to the entryways of MOSFETs for enhancement through 100ohm resistor. 100ohm resistor secures the IC and MOSFETs both.

The fast exchanging of MOSFETs creates the current and force is then enhanced to drive the transformer. Here, in the circuit, its referenced to utilize 15Atransformer Use CD4047 IC for 150watts force yield with an appropriate battery.

The reinforcement of the yield relies upon the battery's ah esteem just as the heap power necessities.

For eg battery is 12v 20ah with 15A transformer and burden is 50w, the all out force by the battery is 240 watts yet the transformer gives 150w. The maximum time 50watts burden can run over 240w reinforcement is 4.8 hours.

Significant Keynotes

I am referencing some significant notes to compute yield force and reinforcement time.


Reinforcement time relies on Battery ah esteem as,

All out accessible battery reinforcement power(Ah*Vin)/load power necessity = reinforcement time(in hours)

Yield VOLTAGE INCREASES as the CURRENT DECREASES yet power continues as before provided by the transformer.

Yield power is needy over MOSFETs utilized for each stage, Total tolerable transformer power V*A and obviously battery power input.

Venture UP TRANSFORMER: A stage up transformer is a ventured down transformer utilized in a turn around way. This implies the optional side utilized as essential and essential utilized as auxiliary. Only transformer for inverter reasons for existing Use CD4047 IC are150wattS inverter utilized in a switch way and for the most part have a hight amperage like 5 amp,10 amps,15, or even 25 amps,

I trust you all enjoyed the circuit just as the clarification of each stage. Kindly notice your perspectives in the remarks. Much appreciated.
