DC-DC Zeta Power Converter: Ramp Compensation Control Design and Stability Analysis

Abstract

The design of robust and reliable power converters is fundamental in the incorporation of novel power systems. In this paper, we perform a detailed theoretical analysis of a synchronous ZETA converter controlled via peak-current with ramp compensation. The controller is designed to guarantee a stable Period 1 orbit with low steady state error at different values of input and reference voltages. The stability of the desired Period 1 orbit of the converter is studied in terms of the Floquet multipliers of the solution. We show that the control strategy is stable over a wide range of parameters, and it only loses stability: (i) when extreme values of the duty cycle are required; and (ii) when input and reference voltages are comparable but small. We also show by means of bifurcation diagrams and Lyapunov exponents that the Period 1 orbit loses stability through a period doubling mechanism and transits to chaos when the duty cycle saturates. We finally present numerical experiments to show that the ramp compensation control is robust to a large set of perturbations.

“…One of the primary advantages of this design is that leakage inductance is avoided. Although the cost i lower, the circuit design is more complex [54]. Te inductance and capacitance values are calculated by.…”

“…Te basic architecture of this converter is illustrated in Figure 10. For N number of cells, this topology consists of 2N + 4 switches, two diodes, one capacitor, and one transformer [54,55]. Cell-to-cell, cell-topack, and pack-to-cell energy transfer systems can be possible with a push-pull converter polarisation to adjust the polarisation of voltage that will impact the transformer's primary winding in response to the trigger signal.…”

“…The need for DC-DC switching power converters is growing as more feasible alternatives to traditional carbon-producing energy sources emerge [1]- [4]. DC-DC power converters are compact and dependable power conversion systems [4]. The use of DC-DC converters in this application, on the other hand, adds new problems to the system [5], [6].…”
