DC-DC conversion is the chief stem of PowerElectronics and is progressing rapidly. Many new topologies are still created every year. The Zeta converter is another converter topology to provide a regulated output voltage from an input voltage that varies above and below the output voltage. The benefits of the Zeta converter over the SEPIC converter include lower output-voltage ripple and easier compensation. The nonpulsating output current of the Zeta converter allows for the use of small output capacitors for satisfying the load voltage ripple requirement. The objective of this paper is to design and implement the CCM mode operation of non-isolated Zeta converter. The design formulas for the continuous conduction mode (CCM) are given. This paper deals with design and steady state analysis of closed loop non-isolated Zeta converter using PID control technique. The simulations have been performed by using MATLAB/Simulink. Through simulation it is confirmed that a PID compensation method improves the output response of the system.

“…Simplified steady-state analysis of the PWM Zeta converter for both continuous and discontinuous inductor current modes was described. Treating the converter with separate inductors as a particular case of the more general coupled-inductor case, the analysis results cover both the converter versions coupled and non coupled inductor [6].…”

“…The signals are sampled at 50 kHz, the inductor current for an inner feedback loop and the output voltage for the outer feedback loop. The equation to determine the relation between the output voltage and the inductor current, defining the outer loop G2, is defined using the technique proposed by [12] and can be expressed as (1).…”

The purpose of this paper is to show a high performance digital control technique of single phase inverters with internal state feedback. The study proves that the high speed processor allows an excellent output signal waveform, even in critical conditions. The reduced computational effort is an attractive feature. That is obtained by using fixed-point arithmetic and proportional integral compensators.Keywords -Digital Control, inverter, compensator, inner/outer loop, microcontroller.

“…The utility of the averaged model for simulation purposes, using dedicated software products such as SPICE ® , SABER ® , MATLAB ® , has also been largely proved (Sanders and Verghese 1991;Ben-Yakoov 1993;Vuthchhay and Bunlaksananusorn 2008). This kind of model is useful for analytically expressing the essential dynamical behavior of power electronic circuits, both in continuoustime (Middlebrook 1988;Rim et al 1988;Lehman and Bass 1996) and discretetime domain (Maksimović and Zane 2007).…”
