Full-bridge single phase inverter unbalanced DQ control

Single phase Full-bridge 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 using only alpha-beta to d-q conversion. In unbalanced d-q control one of the orthogonal component either alpha or beta is taken as zero.
The inverter is fed by a dc source and the output is driving stand-alone resistive loads.
