Boost converters are an integral part of any solar energy system. In order to obtain maximum possible energy from the solar system multi-phase interleaved boost converters are used. This paper presents the small-signal ac modelling and closed loop control of three-phase interleaved boost converter. State–space modelling methodology has been adopted to have linearized equivalent model of the boost converter. The interleaved three-phase boost converter is averaged over its one switching period and perturbed with small ac variations and finally linearized around its quiescent point to have a small signal ac model.  Type III compensator is employed to improve the frequency response and closed loop control of three-phase boost converter. The controller design procedure is discussed in detail. The effect of right-half plane zero in non-minimum phase system and the appropriate pole-zero placements to overcome the maximum phase lag in such system is discussed. The compensated closed loop system is tested for load variations to observe the transient response.</p><p> </p></td></tr></tbody></table>

In this paper, Zero-Voltage-Transition (ZVT) two-cell interleaved boost Power Factor Correction (PFC) converter for voltage source Inverter (VSI) fed permanent magnet brushless DC motor (PMBLDCM) drive has been proposed Scheme reduce the torque ripple of BLDC motor drive and also reduce the switching losses of VSI for Which an auxiliary circuit is designed and added to the interleaved boost converter.  For achieving soft switching, only one switch is used in auxiliary circuit which reduces the torque ripple and switching losses. In this proposed control strategy, the DC link voltage is controlled with interleaved boost converter which is proportional to the desired speed of the BLDC motor. In this paper, six switch and four switch VSI is also implemented with interleaved boost converter topology. A comparison is made between the six switch and Four Switch VSI fed PMBLDC Motor drive and Torque Analysis as been done. To validate the proposed work, results are presented. The results showed that proposed converter control strategy operating under soft switching mode improves the efficiency of the drive system with PFC feature in wide range of the speed control.
