A novel algorithm of MGWO-based PI controller for a single-stage grid-connected flyback inverter with ZVS

An effective approach on zero-voltage switching scheme for a single-stage grid-connected flyback inverter along with the introduction of Modified Grey Wolf Optimizer technique based proportional integral controller is proposed. A focus soft-switching attained by means permitting grid-side negative current bidirectional switches held in transformer’s secondary side. Consequently, there discharge metal–oxide–semiconductor field-effect transistor’s output capacitor. This function led primary switch to turn ON at condition zero voltage. Therefore, it essential optimize reactive level attaining switching. Generally, basic Optimization has some more disadvantages accuracy-solving and less capability finding fitness solutions. Hence, overcome this, optimizer can be modified further enhancement optimization process. pulse width modulation used controlling switches; thereby triggering takes place which results decreased total harmonic distortion. Finally, simulations carried out distortion helps illustrate effectiveness suggested algorithm. 24-V, 325-W prototype been verify proposed system.
