Abstract
Abstract:
The paper presents a novel phase shifted SPWM control scheme
for cascading two cells to form a “3-5-9 hybrid inverter with
improved harmonic suppression. Modeling of the hybrid inverter
from first principle is introduced and a standard control law is
derived for further analysis and development of the model. A new
balance circuit for DC link voltage control is designed and tested.
Combined with individual voltage control, a complete control scheme
is developed. Detailed MATLAB simulation and experimental
results are obtained for further validation of the adopted topology
and the control scheme
