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
