Three phase off-grid inverter is driven using Sine PWM. The sine references are generated using a Harmonic oscillator. The closed loop control is implemented in synchronous reference frame, by converting three phase quantities in d-q synchronous reference frame.
The inverter is fed by a dc source and the voltage is maintained at reference value across resistive load.
