How to make 200 Watt Inverter

2 00 Watt Inverter This circuit diagram. Built based on IC CD4047 inverter circuit can convert 12VDC to 220VAC and 50-60Hz frequency and Square wave signal. In this use IC CD4047 Square wave Oscillator at 50Hz and use LM358 for buffer circuit. The transformer is 12V-0-12V Primary and 220V Secondary. Power Transistor IRF250 x 2 For driver transformer 220V ac and other Power Transistor mosfets IRF540 is also use. IC CD4047 will work in the astable multivibrator mode. In the CD4047 are pin 10 and 11 are Q and ~Q from. This AC is given to the step up transformer of the secondary coil. 220VAC- up to 200w transformer from 12V lead acid battery. 200 Watt Inverter circuit diagram:- PCB Board:- Components Required:- 12v Battery Op-amp LM358 IC – CD4047 RED LED(1) 470R ohm Resistor (2) 1k ohm Resi

How to make Temperature controlled circuit

Temperature controlled home automation In this project, we are going to make a simple Temperature controlled circuit using Temperature Sensor LM35.This circuit will be automatically on or off your any AC home appliance according to temperature. We also adjust the temperature by the Variable resistor in the circuit. . When you set the Temperature value at fix Temperature ( 35 Degree Celsius ) then temperature goes above 35 Degree Celsius then fan will switch on automatically and if temperature goes below 35 degree fan will be automatically switched off. Temperature controlled circuit diagram:- Components Required :- 12v Battery IC 7805 Temperature sensor LM35 Op-amp LM358 1k ohm Resistor (3) 10k ohm Resistor (1) 4.7k ohm Resistor (1) Variable Resistor 10k LEDs (Red and Green) NPN Transistor BC547 (1) Diode 1N4007 Relay 12v Bulb or any AC appliance Capacitor (1000uF and 100uF) PCB :- Working:-
