Ur circuit schematic working well. Pwm controller circuit. Preset r1 can be used for fine tuning of the oscillator frequency.
The sg3524 ic chips is a fixed frequency pwm pulse width modulation voltage regulator control circuit with indifferent outputs for single ended or push pull applications.
In order to increase the efficiency of the pwm inverter the electronic circuit is highly sophisticated with battery charge sensor ac mains sensor soft start facility output control etc. The pwm controller circuit uses pwm ic ka 3225 or lm 494 these ics have internal circuits for the entire operation of the pulse width modulation. I ve been using it as a backup to power up all my house when outages occur since aprox. Pwm inverter circuit diagram.
