A Novel VFVDC Optimized Full Bridge Inverter Control Strategy for Independent Solar Power Systems

This research explored the independent solar power system (ISPS), including maximum point tracking (MPPT) technology and DC (direct current) to AC (alternating full-bridge inverter (FBI) control technology. study combined perturb observe (P&O) algorithm based on output voltage strategy proposed optimized FBI ISPS. The variable frequency duty cycle (VFVDC) had adjustable cycle. VFVDC was compared with sinusoidal pulse width modulation (SPWM). When of at a low level, operating 10 kHz. Conversely, when gave high level output, 1 improved switching loss 4 MOSFETs in thus performance harmonic amount. To further verify system, this used MATLAB compare SPWM method. simulation results verified that total distortion (THD) = 1.02% better than method THD 3.23%, then pass filter (LPF) volume reduced. Finally, actual ISPS for measurement verification. can operate stably effectively, be fulfillment electricity needs.
