MODES OF OPERATION There are two modes of operation in itS I S A N D E V A L U A T I O N Feedback control is usually incorporated into the converter circuit to regulate its output voltage typically by means of pulse width modulation (PWM) To facilitate the feedback control design or system stability analysis the linear model of the converter is needed. The SEPIC converter consist of an active power switch, a diode two inductors and a capacitor and is thus the fourth order non linear system. Cc allows utilization of transformer leakage inductor ZVS (zero voltage utilization) to achieve operation and to limit the peak voltage stress of main switch S. Active clamp circuits in include switch sA and clamp capacitor. Lm is the magnetising inductor of the isolation transformer D is rectifier diode. Lr is the resonant inductor including the transformer. The capacitor C is medium for transferring energy from the source to the load Cr is the resonant capacitor. S and Sa are main and auxiliary switches respectively Cs and Co are the clamp capacitor and input capacitor respectively.

Its main advantage to the dc to dc converter elevator reduces type or cuk is that the SEPIC converter maintains the output voltage polarity same to the input voltage which cannot be done with others As the SEPIC converter a switch mode circuit, its behaviour is strongly dependent in the continuity of the inductor current and capacitor voltage Due to this the input current example of the SEPIC is smooth (because of the inductor ) and the output current signal is chopped (because of the diode feeding the output ) then the energy is passedĪcross the capacitors are widely used because of its very high efficiency (around 96%) in PC power supplies ,battery chargers DC motor power systems and different industrial applications Design Discription For An Active Sepic Converter Circuit configuration of the proposed isolated buck boost type of active clamp L is input inductor. Different designs are used using active and passive components Systematic Discription Of Sepic Converter The SEPIC type dc to dc converter is a power electronic supply voltage at the output and can be smaller and higher then the received input ,this is done by switching techniques with semiconductor Devices such as diodes and transistors i.e SEPIC converters are usually designed with coupled inductors L1 and L2 in order to reduce production cost and to reduce the input current ripple. Conversion has to be achieved ,all these characteristics are obtained in SEPIC Dc to dc power conversion system can be realized by different circuit topologies like for example(buck boost, buck boost) are most widely used. But it is not easy for conventional power converter design to maintain high efficiency especially in up and down voltage.

Different portable electronic appliances have been benefitted from a power converter which is able to achieve high efficiency with a wide input and output ranges with a small size. Introduction SEPIC is a dc to dc converter and is capable of operating in either step up or step down mode and widely used in battery operated equipments.It is considered to be a fourth order dc to dc converter capable of delivering an output voltage which can be greater than or less than the input voltage.
