Recently, “KY-Boost-Converter (KYBC)” has been extended as a substitute between PV-system &AC-load. DC-level is enhanced using Boost-Converter (BC) &its yield is inverted and AC is applied to a three-phase-load. This work suggests the combination of KY Boost converter with grid-connected-three-phase-inverter-system (KYBCTPIS). The KYBC is exploited to escalate the voltage-gain. Simulink-models are developed for (-Proportional*Integral) PI, (-Fractional*order-proportional-integral-derivative) FOPID-controller (*proportional resonant) PRC based KYBCTPI-systems. This effort mainly compares the time-responses of PI, FOPID controller and PR controller based KYBCTPI- systems. The investigations indicate that the response of PR Control based KYBCTPI system is better than PI & FOPID based KYBCTPI systems
