What is a closed-loop control inverter?
Closed-loop control inverters are gaining ever-wider application in various power scenarios such as medical, industrial and military. The requirements for the steady-state and dynamic performances of their output voltage waveforms are becoming increasingly demanding under various load conditions.
How a single phase grid connected inverter is driven?
Single phase grid connected inverter is driven using Sine PWM. The sine references are generated using a PLL and 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.
How does a PWM inverter work?
Its deviation from the sampling voltage is set as the current of inner current loop after passing through the voltage loop PI, which is compared with the sampling current, and then with the triangular wave to output the PWM wave. The inverter con-trol algorithm is implemented in the interrupt of the program. The flow chart is in Fig. 7.
