“…Among the different non-conventional sources solar energy holds the most potential to meet the energy demand [1]. Normally photovoltaic array is used in integration with DC-DC converters such as boost converter, buck-boost converter, buck boost converter, Cuk converter etc., Buck boost converters are preferred as they produce lesser average output voltage in buck mode, which can be used for applications such as charging of batteries of lower rating.…”

In this paper, a closed loop control scheme for DC-DC SEPIC converter that realizes a regulated dc output voltage is discussed in detail. The converter equations corresponding to different modes of operation of the converter are developed. The proportional integral controller using loop shaping method is systematically developed with the help of state equations obtained from the converter equations. Simulation studies are carried out to confirm the effectiveness of the suggested control strategy under large perturbations.

This paper proposes monitoring of the dual dc-dc converters that independently operate of each other in the same topology (Buck-Boost). The dual converter structure is proposed to implement asymmetrical string inverter that is intended to be used variously arranged PV strings. The converters are operated by independently running MPPT algorithms. The converters are supplied by programmed dc sources emulating freely arranged solar arrays, and different loads are connected to each converter output. The converters allow using independent power sources like hybrid power techniques owing to these features. Current and voltage sensors measure the output powers of each converter, where the obtained values are evaluated by P&O algorithm on MCU and the PWM signals are generated. At the same time, obtained values are transmitted to computer by a microcontroller on optically isolated UART to USB unit. The received values are saved in a database to enable historical and instant analyse capability of the converters.

“…CUK converter is better than buck-boost converter as it has continuous input-output current and supplies energy to load both when the switch is open and close. CUK circuit has reduced circuit parameters than SEPIC converter, hence the cost is also reduced [7], [8], [9], [10].…”

In this paper, analysis and design of a novel single phase AC-DC CUK converter circuit has been proposed where Power Factor Correction (PFC) controller scheme has been used in order to obtain better performance than conventional converters. Closed loop technique is applied to the bridgeless converter in order to achieve low input current, Total Harmonic Distortion (THD) at input AC mains along with near unity power factor. Performance comparison between open loop and closed loop of the proposed converter is made without filtering. The problems arise with open loop is sufficiently minimized by using power factor correction controller. The performance comparison between proposed and conventional CUK AC-DC converter operating in Continuous Conduction Mode (CCM) is made based on circuit simulations using PSIM softwere.
