Introduction Hey everyone in this session we will discuss about working of PWM based motor speed controller, LED brightness controller. Components Required 1)LM555 IC 2)IRFZ44N or any N-Channel Mosfet 3)1N4148*2 4)1N5819*1 5)10nF, 100uF*1, 470uF*1 6)200K VR 7)330R, 1K, 2.2K, 10K 8)LED*1 9)LM7812 Regulator IC 10)100uF Inductor Working For controlling motor speed or LED brightness we generally use linear regulator which is simple in making but they don't have better efficiency as compared to PWM based controller so for that reason I made PWM controller with the help of very famous IC LM555, which is used in astable multivibrator mode. For controlling output we need to control the on time and off time of the switching mosfet it means we need to adjust duty cycle from 0% to 100% so that we can get desired voltage at the output. Here we see a inductor which is used to smooth the output. Testing  For the load testing we use 12v motor and 4v high power led. Circuit

Introduction Hey everyone in this topic we will discuss about inverter and working circuit with load test and efficiency. Components So lets take look at components we need to make this circuit - 1. SG/KA3525 IC 2. IRFZ44N N-Channel Mosfet 3. ATX PSU ferrite core transformer 4. 4700uF capacitor 5. Variable resistor - 10K*4, 500K*1 6. 16-pin IC Base 7. Capacitors - 1nF*2, 100nF*4) 8. Resistors - 100R*1, 1K*10, 5.6K*1, 10K*6, 100K*1 9. LED*1 Working First we have to look on the main part which is controller circuit based on KA3525 IC having feedback to control output voltage or auto voltage correction which is done by PC817 optocoupler for isolation from high voltage to low voltage side. The main component, transformer which is taken from old computer power supply and for winding of primary and secondary there's no complicated calculation is required because for step up transformer like inverter make total of 8T with 0.6mm wire of 5 layers in secondary with (4T + 4T) centered tap, an...
