This inverter circuit contains three stages, pwm switching pulse generator; Users can adjust the width of pwm using a variable resistor shown in the feedback circuit.
Sg3524 pwm inverter circuit diagram.
Pwm or pulse width modulation is used to keep the output voltage of the inverter at the rated voltage(110v ac / 220v ac) (depending on the country) irrespective of the output load.in a conventional inverter the output voltage changes according to the changes in the load.to nullify effect caused by the changing loads,the pwm inverter correct the output. The intersection of and waves determines the switching instants and commutation of the modulated pulse. Pwm modified sine wave inverter circuit. Resistor r2 and capacitor c1 sets the frequency of the ics internal oscillator.
