This model demonstrate the basic design and fundamental operation of a
Pure Sine Wave Off Grid inverter with the following specification

Input Voltage: 24V DC
Nominal Output Voltage: 230V AC
Rated Power Output: 1kVA See Linear Transformer Block
Modulation Method: Sinusoidal PWM See PWM Generator Block
Power Frequency: 50Hz See PWM Generator Block
Carrier Frequency: 10kHz (200*50Hz) See PWM Generator Block
Control Method: PI Voltage Feedback Control

THD: < 1.2% at rated power output
THD: < 2.5% at 50% of rated power output
THD: < 5% at > 25% of rated power output

For simplicity the input DC link capacitor and output LC filter were
